What confuses me is that Disturbed's SoS is clearly a marmite version (I prefer it TBH, the original is just played too much for wistful and optimistic, not dark and miserable enough for me), but regardless of this it could be uber sh!te and the worst cover version ever, but that doesn't make Disturbed the worst band ever, <checks> this is worst BAND not worst SONG.
There are loads of examples of lemons by decent bands, what's sought here are surely truly awful examples of bands through and through.
