So an artist shouldn't release their album unless they have a chance to win a Grammy for it?

If everyone went by that logic, very few people would be releasing every year.
No one is winning anything next year with Adele in the running. That's just something we have to accept, and at least Adele is worthy of the praise and awards.
If there's a good thing to be had out of this, the pressure Gaga and her team will be under because of Adele's immense success should push them to do their best. If we get a good album and era, I could care less about awards.
