The thing I like about baseball is that it's one-on-one. You stand up there alone and if you make a mistake it's your mistake. If you hit a home run it's your home run.
I think the true test of a pop song for me and I've talked to a lot of other writers about this is you take your demo you pop it in your car and you drive down Sunset Blvd. to Santa Monica and that's the Hollywood car test.
