Do you rely on the Google Play Music app on your smartphone? If so, and you currently rock an SD card with cached and stored-for-offline-playback music, you may want to check out this bug that's reportedly causing some consumers to lose their music collection. We've not yet been able to confirm the reports, but it seems the app is accidentally deleting music stored on microSD cards
It appears to only affect those with cached and stored-for-offline-playback tracks and microSD storage enabled in the Google Play Music app. For everyone else, you should be able to enjoy a hassle-free music experience. Luckily for those who happen to be affected, Google is aware of the issue and is working on a fix. The company replied to a consumer's support ticket with some details on the problem:
"Music that has been downloaded for offline listening, either to the internal storage or SD card, should never be deleted without the user initiating the deletion. This is an actual known issue with this service. The good news is that we are aware of this issue and are actively working to get it fixed."
The good news is it only appears to be All Access content that's affected. If you're not using the service, you should be golden. Let us know in the comments if you've experienced this issue.
