I've been a published songwriter with London Records years ago. I'm getting back into my writing again and hope I still have the "juice" I once had (ha-ha).
Anyway, there's a theory out there (especially from old-schooled master songwriters like Barry Manilow, Neil Diamond, Paul Williams, Burt Bacharch, etc.) that you should start writing songs by coming up with great titles to work with before anything else.
