This is a very fine example of multi-tasking.
We need a recorder especially adapted to be fitted to a bike so we can record just what musical ideas come to us as we ride the bike through a traffic jam. A taxi driver's remarks may inspire some people.
After that, when we get home in the evening, it is time for a lot of hard graft to turn the recordings into a musical idea - followed by more hard graft to knock all ideas into a commercial song.
Apologies for the English scenario but please do your own adaptation. You could just work up a lyric. I am not clever enough.
