1. Samsung 2. S5 3. KitKat 4. Music (the stock application) crashes on opening it. I have tried deleting it's application data & cache but still as soon as it starts loading it crashes. 5. Not rooted I factory reset about 2 weeks ago. And tonight I decided to remake the rest of my playlists in Music. PowerAmp can export system playlists to .M3U8 files so I went to do so. But PowerAmp wasn't finding the new ones I created even after telling it to "rescan". SonI uninstalled & reinstalled it. It found them no problem. But Music had found the duplicates/back-ups so I stuck a .nomedia file in the Playlists folder. Worked fine for the evening. I opened Music again and saw my system playlists were missing so I deleted the .nomedia file. Music hadn't found them for a while so I forced closed Music to reopen it to rescan for them. But it crashed as soon as it loaded. I cleared the cache first and still crash. So I deleted its application data. And it still crashes. I have uninstalled PowerAmp and deleted the system playlists thinking maybe something was with that. I did a wipe cache partition but no dice still. I use Music daily and I really want to get this sorted.
