When some one does a cover song, its either of 2 things... they acnt think of shit else to do, or they did it because they love the song..

Tribute to Ramones was a pretty decent cd which had multiple bands doing Ramone covers; Offsprings - I Wanna Be Sedated ; Is a good example.

I personally, my top 10, have 2 songs of Pink Floyd in there. The Trial from the Wall album.. I must have watched that part of the Wall movie so many times..

What pisses me off more than a shitty cover song is taking a good classic rock song and turning the beat into a rap song.. like Crazy Train... everytime that song hits my random playlist.. I think of the rap version and immdiatly change the song
