Mariah Carey. I have ALL her albums and have been a fan since i was in highschool, probably at age 13? 14? Why she's my favourite musician is because she writes, sings AND produce her own songs! and the songs are nice! makes you want to repeat it over and over (well, atleast in my case :)
Regine Velasquez. My brother introduced me to the world of Philipino music when he was attending school there and i never looked back ever since. To be honest, i know more about the Philipino music scene than Malaysia's hahaha!
Why i am a fan of her's? the voice says it all.
She doesn't compose her own songs but she sings it like she owns it.
