Hi Tim, there is no wrong way to write music. Ask 29 different people and you may get 29 different workflows.

I don't have one approach to my songs. Sometimes I will just input some chords into BiaB, select a style, and then choose a lead. Sometimes a lead will pop into my head and the above workflow is reversed. On the rare times I sing though I always have the lyrics first, then I will choose one of the above workflows.

The only things I would caution anyone about is to not use the same workflow every time and don't be afraid to get out of your comfort zone on occasion. Mixing things up can be very rewarding. YMMV

Whenever I get something stuck in the back of my throat, I dislodge it by drinking a beer.
It's called the Heineken Maneuver.
