There is absolutely no way that would get radio play. Way too long and people wouldn't have the attention span to listen to auto-tuned imrpov singing from Nate. I agree it's a great song, but not for the radio.
Yeah, you're right, no way that song would get radio play. One song though that I always thought would be a great radio song was All Alright, so it'll be interesting to see what they choose next if they decide to release another single.
