YYYs can headline because of the following reasons:

1. They're awesome.
2. People like them and listen to them and buy their music.
3. New album.
4. Cozy with Goldenvoice.
5. Though they may have lost their "steam", as many people have recently stated, I can see Goldenvoice giving them that spot to build them up back to what they were before they took the time off.
