Google Play Music is trying to update. It's a 6MB download. I have insufficient storage space.*
There's 120MB left on my internal storage, 2GB on the "phone storage" partition, a whopping 7.2GB on my SD card**.
I have insufficient storage space for a 6MB download.

** It would be a lot less if I had direct control over where Google Play stored its media. Currently it assumes you want it on the "sdcard0" mount, which is how the "phone storage" partition on my phone identifies itself ..
