Now that 3 original songs from the Glee Cast are out, some are saying that they are better than their covers, or that they should just stick to them and not bother with songs they've actually made themselves.
Yeah, their original songs are really amazing.. but their covers are as well. I'd hate to take away their amazing covers and have only original songs, even though it wouldn't matter to me if that's how they did their show since they started.
Even if they did this, it'd be pretty hard.. making like, 4 original songs per episode? Since they do about that many per episode, sometimes even more.
