Although only 19 years old, Amy is an artist who has wisdom beyond her years, illustrated clearly within her cleverly beautiful, humorous, energetic and at times poignant lyrics - she sees the world for what it is and isn't afraid to tell you what she thinks.
And hers is certainly an opinion when, combined with outstanding musical talent, is instantly recognisable as something novel, unique, and easy to relate to, qualities recognised by all who have had the golden opportunity to hear her and have resulted in her signing to label Mercury Records last year.
Yet little did Amy know when, at aged 12, she first picked up a guitar, her profound love of music would lead to the very edge of stardom - where she now stands.
"It all really started with Travis," she explains in her soft Glasgweigan accent, of the spark which catapulted her into the world of music.
"We were on a family holiday and my nanna had given us all a tenner to spend on sweeties, but instead I bought the Travis' album 'The Man Who' and just listened to it non-stop from that moment on.
"I found out that they were playing at T-in the Park that year and begged my ma to take me. She did and I was blown away by seeing them play live. I was so inspired by seeing them on stage and how the music all came together and I just thought to myself then: 'I want to do that!'
"After that I bought a Travis chord book and got one of my dad's guitars and sat down to teach myself to play. The first song I ever learnt to play was 'Turn' and then I think I learnt the whole of the Travis back catalogue over the next year and a half!" she laughed.
There came a point, however, when learning and covering others' works were not enough for Amy and she plunged into the next step of her musical career by tentatively putting pen to paper and writing her own material.
"I find that writing songs lets me get my feelings out, it helps me to relax, but although I don't mind people listening to my songs or reading the lyrics, it is something that is very personal to me," Amy revealed.
"I can't have people reading my lyrics while I'm in the same room or in front of me. They really are very personal and if someone is reading them with me beside them I feel like they're looking inside my head. I either have to leave the room or sing them out loud rather than sit with someone reading them!"
Becoming so lyrically aware at a young age held Amy in good stead for her first big break which came whilst she was in third year at school with a visit from community music group 'Impact Arts'.
Made up of local musicians, including a member of 80s Scottish pop band 'The Bluebells', the songstress' talent was spotted and nurtured, resulting in her performing acoustic shows around the culture capital - just her, 15 years old, and a guitar.
As Amy explained: "They (Impact Arts] were professional and knew the industry so it was really good that they got involved. I would play my songs to them and they gave me a lot of great feedback as well as getting me gigs. They gave me so much experience and confidence that I think now was vital to get at that age, and it really inspired me to keep going."
Soon she had a regular spot in the Starbucks cafe of the city's Borders Books branch, as well as travelling to the Edinburgh branch to perform and was also landing gigs in popular music venues such as the Barfly.
Experience and confidence growing, such shows taught the young talent a great deal, something which Amy is acutely aware of as she continued: "Playing in Starbucks was something different as I soon learnt that people weren't generally there to listen with 100% interest to me - people were chatting and enjoying coffee.
"It made me deal with the fact that if people aren't listening to me it wasn't anything personal and that I shouldn't take it as such. I see other performers get stressed or annoyed if people aren't paying them their full attention, but through the Starbucks shows I learnt how to cope with that and avoid feeling disappointed."
Not only did such gigs teach her to be humble in her music - as well as how to sneak into bars underage - Amy also found great inspiration in playing with musicians much older than herself.
"Me and my friends used to sneak into the Brunswick Cellar and sit in a dark corner every Saturday so I could take part in the open mic night," she admitted.
"I always got a good reception and when people who were older than me came up and were really interested in my music, and really complementary about my stuff, it meant such a lot and gave me the boost to keep on plugging away at it."
At the age of 17, with acceptance to two universities, Amy decided to take a year out and focus on her music. This proved to be a wise decision, leading to an even bigger break when she replied to an ad in the back of NME music magazine detailing a new production company looking for unsigned artists.
Melodramatic Records took one listen to Amy's demo and called her in for a live performance - she was instantly signed to the fledgling label - which in turn lead to her biggest break to date, signing to Mercury Records.
Amy elaborated: "Signing to Melodramatic was a pivotal step. The first year with them we really worked hard on my demos, on my stage presence and my recordings so it gave me a lot more confidence and inspiration to pursue more things.
"It was through them that I signed with Mercury and I still find it totally bizarre - if someone had told me a year ago I would be signed to them I would have told them to shut up and stop being so daft!" she chuckled.
"Melodramatic sent out my demos and then we went round all the big labels, me and my guitar, going into offices and playing for people. I didn't think that was the way it still happened, but it was all really exciting, and the guys at Mercury were really excited when they heard me so things just took off from there."
The last year with Mercury has seen Amy record her debut album, which features her first single - 'Poison Prince' - due for release on May 7 (due for download release April 9).
"Everyone who was involved in the album really got on board and we all got on so well that it was such great fun to do. My band are all really close and they were all recording with me so it really was like spending time with friends than like working," Amy commented.
"The last year or two has been weird as if none of this had happened I would be at uni studying, and to be honest I'm quite what they call 'work-shy', so I don't think I'd be doing very well at it! This is hard work, I'm up early every day and busy going here and there, writing and recording, but I love it and I just want to keep on doing it."
Definitely one to watch, the hype surrounding Amy Macdonald is steadily growing, yet the 19 year old is one who lives up to such promises. But do comparisons to recent Scottish big hitters KT Tunstall and Paulo Nutini unnerve the teen sensation?
"It's really nice for people to say that as they are both such extremely talented people, but I think we all play such different music that the only thing that I have in common with them is the fact I play a guitar and am Scottish," she replied, adding: "I'll be chuffed if I'm ever half as successful as they are though and it really is an honour that people put me in the same category as them."
And islanders can hear from themselves just what is so special about Amy Macdonald when she performs at the Woodland Centre, Stornoway on March 9. It is certainly a gig to look forward to - just as Amy herself is looking forward to her arrival on Lewis, as she concluded happily: "I think I've been practically everywhere in Scotland, but I've never made it up to Lewis before. I'm hugely patriotic, so I'm really looking forward to seeing a part of the country that's so far away. I just hope it's nice weather!"
Tickets for Amy's show at the Woodlands are available now at the An Lanntair Box Office - certainly not a show to be missed by island music lovers.
