Bad ones:
N.Y.C.C. (New York city collection:LOL: )
"Highway to hell"
their version of "fight for your right" was ok but not as good as the original.
Abba-teens(A-teen nowadays), all their songs are crap.
Good ones:
Wasn't run dmc's "it's like that" a cover?
In my opinion both versions of "Endless love" are good, but that might have to do with that I have good memories of the song.
"American pie" by Madonna is much better than the original.
