I thought I had a bad aux cable in my car. i was listening to a play list of mixed songs purchased from Play Store and some uploaded with music manager. I've had this playlist for a long time and never had issues. My playlist also was pinned to my Galaxy Nexus but not on my tablet. long story short songs i have uploaded either from Itunes or AmazonMP3 to google sound terrible. Some sound like they are playing very fast and some sound like the vocals are so low you can only hear music. to me that tells me they are corrupted. I get to my PC launch Play Music in browser and the same songs streaming from google sound exactly the same on my device. I cant pinpoint exactly when this happened but sometime within the last month. Has anyone had this issue with their music?
