Of course, they'll want part of the royalties of any million dollar hit!

Bill, try this instead. Use the Melodist feature.
Take a song you like, and a style you like, write the chords in, and then using the Melodist feature, set it so as not to write over your chords. Now, you can gather parts of the song, or the whole song if you like, and put it together into a finished product.
If you don't have a favorite song, just don't put any chords in at all, and Melodist will come up with those, too.
