I didn't have a favorite I could point to at any time in my early life, although I can say with some clarity what I listened to when I was younger:
Prior to/ or early teenage years:
- Huey Lewis and the News
- Rush
- Asia
- Abba
- Van Halen
- The Cars
- Night Ranger
- Def Leppard
- Wham
- New Order
- U2
- Various classical music my folks had on record.
Teens:
Bon Jovi
Iron Maiden
Dokken
Metallica
Depeche Mode
Ozzy Osbourne
King Diamond
Steve Vai
Bach (mostly Andres Segovia at the time)
Dead or Alive
Deep Purple
Dream Theater (actually early 20's for these guys)
I liked a lot of other music too, including much more classical reaching adulthood - but these I typically listened to more than others when I was younger. So my favorites includes a lot of musicians.
