80's and 90's:
Twisted Sister, Helix, Scorpions, Kiss Def Leppard, Bon Jovi, Skid Row, Extreme, Winger, Metallica, Iron Maiden, Guns & Roses, Megadeth, Pantera, Testament, Triump, Harem Scarem and most of the hair and heavy metal except Dokken (don't know why, never got into them)
From 1992 I listened mostly only power metal :
Blind Guardian, Helloween, Gamma Ray, Edguy, Rhapsody, Avantasia, Sonata Arctica (can't stand Tony's voice anymore, find it annoying)
Now:
Dream Theater
DGM
Noveria
Primal Fear
Allen Lande
Pretty Maids
instrumental like Marco Sfogli, Andy James, Andy Timmons
and some power metal bands...
