If you wish to use a song, you contact the Publisher and purchase a LICENSE to play the song in Public. if Michele played this song at a rally, she BOUGHT the Right to do so. Tom is being petty.
If not, I'm not sure what his complaint would be, since he agreed to give up ownership rights.
Of course, the MSM will point out that Bachman doesn't have Petty's support to use her own campaign music every chance they get, so it probably is best to just drop it for Michelle.
If ‘one-sheet’ TP owns the rights to publishing, he can do as he sees fit. If he does not she can buy the rights from whoever does, play it according to the terms she bought usage rights for and he can bitch till the cows come home.
It comes down to who owns the rights.
Amen and it is a pain but that’s the rules.
