Marginally better than Nickelback I suppose, at least they make some attempt to sing. Admittedly, I do like some of Green Day`s stuff as its kinda poppy.
Led Zeppelin has some good songs but they are not the greatest band ever like some people think.
I don't like "old" Metallica and would prefer to listen to Load and The Black Album if anything.
I don't see the big deal about Prince.
The Pop Group are great but I prefer Gang of Four and that being said other than having a somewhat funky sound I don't think those two banRAB are comparable at all. Gang of Four sound like very funky punk and Pop Group are..... free jazz funk dub rock?
