Yep, tastes change, no doubt about it. Growing up, I was exposed to every kind of music imaginable... I went from outlaw country, to blues, to classic rock (Led Zep, Hendrix, et al), southern rock, hard rock, pop metal, shred/neoclassical, to thrash. I've played in hard rock, country, and industrial bands.
I listen to everything I can get my hands on these days!
Changing tastes will make you a better, more diverse player. What's cool is you can take elements from other styles and apply it to whatever style you're playing now.
Got a real cool jazz lick? Throw it in your next metal solo for some variation. It keeps the music fresh and interesting!
