I think it's really whatever Max feels like at the moment when it comes to those song lengths. I'm sure he aims for a certain minimum. Even full lengths are often closer to two minutes.
If he earns as much in Say Anything royalties as he does in song shop then I would be surprised. Maybe in album release years he comes close.
And he's definitely a better artist than Mark Hoppus.
I understand that. He sent out a text about one song being the deepest song he's ever written. Mine was late getting sent. I'll always wonder if it was my song.
