Hey Donna,

Great stuff. Congrats !

You've registered your song with BMI and have an ISI number ? That's all you need, BMI will do the rest.

If it's a major artist, then they may ask for a percentage of the publishing, but that's Ok as you already own 100% of that.

I wouldn't worry about an attorney, they will probably charge an arm and a leg, way above your initial royalties.

Good luck with the song !

cheers, niteshift
