i had to quit listening to them, i was getting depressed.
Stick to their older tunes. Avett Bros have progressively gone down hill the more they release music. If you're into their sound, their older, folky stuff is a lot better than this new Carpenter shit
As for Mumford and Sons, someone said it earlier, you've got to be in the right mood. I like their music, but a lot of it does sound very similar. But if you're into good messages in songs and all they're your guys. It's funny that they're not a Christian band, per se, but have definite faith and religious undertones/inspirations but the mainstream world doesnt push them away. Like they don't realize it or something.
But no, they're not bad. Just sound the same a lot
