Well it was already pretty obvious that I would suggest te Gowan :D! But te might not like it because it's old stuff xD... And it sounds old, te know, like 70s-80s Musica but since te want to try to stuff, try it :). I would also suggest Styx (of course xD) so anyway, here's a little lista of songs te can start with (if te really want to try it) and if te like them just, te know, look for other songs... te know how Youtube works xD te can also cerca for live video if te want, it sounds less old (and shows the awesome Canto skills xD)! Ok I wrote "xD" a lot... probably because I'm talking about Gowan and Styx xD (hahah... -.-)!
Gowan:
A Criminal Mind
Dedication
All the innamorati in the World
Moonlight Desires
Forever One
Dancing on my Own Ground
STYX:

And here are some good other bands te might want to try...

DEF LEPPARD:

Well, there are many più songs and many più bands I could suggest but I think it would kinda be too much xD! Actually, I think I wrote too much stuff already (sorry o3o)...
Anyway, tell me if you're interested in più bands o songs... Oh! And also, tell me what te think about it (even if te didn't like it, I just would like to know ^^). I put the links for the Styx video because it's kind of hard to find good recente ones ;)
Sorry for the long text :S
