Acoustic sets are a bit rubbish, rather than being louder (and therefore better), they're quieter, which is totally lame and the opposite of what I want to hear. (Apparently you're not even allowed to use distortion pedals in acoustic stuff. What's up with that? Useless hippies.)
I think rather than acoustic versions of songs, there should rather be 'ultra-amped' versions, which have extra amps, walls of screeching feedback, and an additional drummer. And videos with dinosaurs fighting zombies in it.
