This is stupid. Why do people think it is okay to cover songs that just came out?
The unspoken rule is the song needs to be at least 10 years old or the band needs to be broken up for at least 5 years. I know some will think this is ridiculous, but it makes sense. Let the band that wrote the song perform it.
This is 100% true, well, I dunno about the 5 year things, but I've always thought you should wait at least 10 years, unless its one of those things where bands cover each other. Like the old BYO splits.
