Is it songs they think that will get them to the final?

Hopefully

Have they done American Anthems yet? I'm surprised there was no Beatle or Michael Jackson Week.

Doesn't really matter what theme it is. Either the theme is so loose so they can sing basically anything or they sem to bend the rules so that they can sing whatever they like anyway.

It will be a week there the contestants sing a Whitney Huston song while breaking in to a rap during it..
