When I was young it was just cheesy pop and chart stuff from the early-mid 90's.
When I was 15 I remember buying and getting into various different artists.
Things like Eminem (Slim Shady Lp +Marshall Mathers)
Also things like Limp Bizkit, KoRn, Greenday, Nirvana, The Offspring, Blink 182 etc amongst many others.
Was listening to more Nu Metal when Linkin Park arrived. Also bands like ill nino, Deftones, American Head Charge, System of a down, Queens of the stone age, Incubus.
I then Starting going more into Heavy metal/Classic rock/Thrash and heavier stuff.
Was listening to Metallica, Iron Maiden, Megadeth, Deep purple, Led Zeppelin, AC/DC, Pantera Sepultura, Soul Fly. Was probably about 17ish by this time (Almost 20 years ago, Circa 2003ish)
I always had a thing for Funk and soul, blues, reggae, indie and many other genres and rap
I listened and enjoyed dance/electro/House some trance.
Fat beats and DJs, but not happy hardcore.
Just adding new artists over the years. My tastes are varied and vast.
In the last 10 years or so I don't really listen to the heavier stuff, but still appreciate it.
I will listen to most things apart from Chart pop and Country which I don't really enjoy what so ever.
Exceptions being Johnny Cash or Willie Nelson.
Don't mind Bluegrass or that, just not the typical country and western ting.
