Hey Guys,
We're both correct. The Title "IS" the Hook. The hook is what is remembered most in the song, and when someone goes to purchase the record, gotta have that title (hook). Not to say you can't have a different hook than the title, there are some (not that many) songs that are titled with something that's never heard in the song, and then that leaves your listener wondering what it's called.
In my opinion, if I was pitching a new song as an unknown artist, I'd want to try to follow what the powers that be are looking for. After you have some clout, you could probably do anything you want.
Those are just the standards though, to each his own.
See, we'll pretty much all on the same page, and It's all good!
Cheers!
Connie
