In 2009, I started creating a seasonal playlist until end of 2011. with no car to listen to CDs, the main time I listened to music, I stopped.
now that I look at it, actually I've been treating songs as influences for a while. I've got up to #34 of earworms at 40-word-year since 2011.
this place seems a better application since a song is likely to have its crux in a brain-washing phrase or line, such as let it go, let it go (Great Big Sea), not some larger unit to sample that represents the appeal. 40-words doesn't allow, by constraint, any repeats and earworms, by nature, repeat.
