Personally I find it hard to think of crap covers. Given my taste in music there's a good chance I wasn't a fan of the song to begin with, so yet another pop group doing it isn't going to make much difference. In fact I tend to reserve my ire for people nabbing samples of perfectly good riffs and then buggering them up by rapping all over it. Kid Rock I'm looking at you. As it is I can think of loads of frankly awesome covers (Gamma Ray doing "Its a Sin" for instance), but I'll try and narrow it down to five.
But first some comedy in the form of
Cradle of Filth - Devil Woman... Now for something a little more serious. .
Motorhead/Girlschool - Please Don't Touch. It was either this or him and Wendy O'Williams doing "Stand By Your Man". I think this is the better song though.
69 Eyes - Lost Boys. Is it really so bad that I want to change the lyric to "everybody knows you're goths..."? >;-)
Hawkwind - Gimme Shelter. A slab of brilliant space rock.
Novembre - Cloudbursting. Barely changes the song, apart from adding their fantastic drumming to the mix. I love these guys.
Ten Masked Men - Hit Me Baby One More Time. Possibly the greatest cover in the universe.
And now for the bad ones:
Helloween - Space Oddity. No. Leave Bowie alone.
Ten Masked Men - Thriller. Not every song is better with death metal. This is the exception that proves the rule.
Type O Negative - Day Tripper (Medley). I'm not a fan of medleys. Especially not when they just aren't very good. Its a pity because their version of Cinnamon Girl is excellent.
