Showtime is so awesome, but I never imagined it as a single. Strange.. Yeah, it would make a good radio single, they should release it.
Do It is so addictive too, that'd make a good single!
All Good Things and Say It Right are very strong though. It's like on the first listen "OMG ITS AWESOME" at least that's how it was to me.
Immediate appeal? People are pretty impatient, if they don't like something on first listen, they'd just change the radio station. Like my mom.
