So, funnily enough, my first concert was Def Leppard and Cheap Trick with another band... Poison.

I can't fault you for not liking either Cheap Trick or Def Leppard. I've outgrown both of them as I've expanded my music taste, but Def Leppard does hold some nostalgia for me. Cheap Trick has some really good tunes, but the best ones never made it on the radio in my opinion. They lost their way a bit in the 80s though.

I have to agree with you about Bon Jovi, Skynyrd, and KISS. I have a friend who is really into KISS and I just don't get it!
