I agree that #12 is probably Mystery, not Rainbow. "Spellbound from start to finish" is something I could see being said about this album. I fell asleep while listening to it on the train, though, but I blame the fact I only had three hours of sleep previous night. I liked what I've heard.
If it wasn't for C&C, I might've thought the voice tidbit was for IQ, but come on, it's definitely C&C.
#10 (the upbeat one) is probably Sieges Even.
Kinda hope the IQ one is #14. I'm not sure anything else fits.
