Q: my guess is that you probably use a mix of the two, because that's how i write my songs too. but are there any specific tips you have just for writing these short jingles?  sorry for the long and winding question
A: you just have to magically think of them, just the same way you can magically think of the words you use when you talk. i don't know exactly how we do that, but i know that you get better the more you familiarize yourself with the playing field. so, for language, we just spend a lot of years in the world listening to people talk and trying to do it ourselves. for music, you can spend a lot of years listening to music and playing around with your favorite instruments. Also, because songwriting involves language, it can be helpful to spend a lot of time free-writing
