The first song I remember thinking "this is my favorite song!" was 'Don't Look Back' by Boston.
Was probably 6-8 years old.
First album I bought? Hell I don't know - some BMG record ripoff thing where I got 8 CDs. I'm pretty sure Gin Blossoms was one of them. I played the hell out of the Blues Traveler CD as well. I think I had Fatboy Slim in there, the Zoot Suit Riot guy (Brian Selzter orchestra?), maybe GooGoo dolls? Some of that mid 90s era stuff all starts to run together. [Reply]
Oooof. Good question. Probably Metallica's Enter Sandman.
Discovering my dad's Motley Crue "Dr. Feelgood" cassette was my first time really picking a favorite artist though. By age 9-10 i had probably collected all of their cassettes.
