my phone keeps re downloading all of my google play music. all the downloading took up my data plan and now i am over my limit. how do i get this to stop?
Eric: On the Play Music->Settings menu, there's a check-box for "Download via Wi-Fi Only". Check it to prevent music downloads over your data connection.
There's also a separate "Stream via Wi-Fi only" option.
Normally your music will only be downloaded to your phone if it has been flagged as "Keep On Device".
