If it's Punk Goes Pop cover i.e. from a pop-genre to a heavier genre: then yes.
It depends. Sometimes there is a really great song sung by a person who isn't that great, or there's a song that just sounds better in someone else's voice. Sometimes you just can't beat the original.
It depends. Sometimes covers can be excellent but sometimes the originals are much better. :)
Originals mostly. There are, I think, two covers I like better than the original versions.
It depends on which one I hear first most of the time. The other times I listen to both interchangeably.
for me it depends on how good it is but i usually prefer the originals. how about u guys?
