Not at all really, my music tastes have broadened, but i haven't grown out of anything. I tend to have phases, Just finished going through an odd phase where for a month or two i have been listening to very heavy metal, and Drum and bass in the large majority.
I didn't really bother with music until i was 11, before that i'd listen mainly to whatever my parents were listening to, Deep Purple, Cream, Dire Straights, Meatloaf and stuff like that.
When at 11/12 a mate from school gave me a tape to listen to with Sepultura, White zombie and some Fear Factory on it, since then i have been hooked on metal, and until the age of about 16/17 that is all i would listen to, as musical diversity is not easy when you are a kid when it comes to your own collecton, as you don't have the money, now i will hapily buy blind but when you can only get 2 cd's a month i had to know i would like them before i bought them.
Then through work i had a mate who had his own decks and got me into dance music, which i was into quite heavily for a year or so, Still listened to metal but listened to a fair amount of dance music.
Started Uni and my rock collection started to expand exponentially as i lived with 2 people who were into different sub genres of metal/rock so started listening to a lot of grunge which i had alwys quite liked but didn't know much beyond Nirvana, then i got with my ex who was a massive maiden fan and after listening to them a bit decided that i liked them a lot.
The past year and a half i have been getting into Drum and Bass, Hip-hop, wierd stuff like Sigur Ros (courtesy of Carzy
) and started listening to a lot of classical music as well.
So my taste has broadened a lot, if yo's have said to me 9 years ago when i was massivley into metal that i would be sat here now listening to the stunning Blood on The Motorway by Dj shadow a trip-hop artist i would have looked at you all funny.
Saying that i will never forget my roots and Metal is and probably always will be my favourite Genre, it just has so many incredible memories attacthed to it for me to leave it, like the feeling of being a little 13 year old kid at my first gig watching Biohazard, or the sheer feeling of awe watching a massive crowd go completely ape**** watching Pantera at Ozzfest, or the pure heaven of seeing NiN live last year.
