mine is pretty simple.
7-8years old - backstreet boys fan
9-11 years old - linkin park and other nu metal
12years old - good charlotte, simple plan, yellowcard, MTV-kind of poppunk
13years old - MCR, Falloutboy (i thought there was such thing as emo-punk, started to get sick of emo and got more hardcore, thanks to certain older friends).
later on during 13yearsold - metalcore (atreyu, a7x, trivium), 70s/80s heavy metal (acdc, metallica, gunsnroses, iron maiden), and some punkrock (misfits, nofx, anti-flag)
14years old - PUNKROCK (ramones, casualties, exploited, etc.), trash metal (slayer, megadeth, venom, etc.) and certain death metal that doesnt sing about satan and hell (children of bodom, arch enemy, black dahlia murder)
until today, i listen to everything i heard before the mcr,falloutboy era. that era, i just thought it was cool and shit. young children have crazy thoughts. lol
