Music app crash under iOS 8.3

First, reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose any data by resetting, but it can cure some glitches.

If this does not work, and to make sure that this is not software related, set it back to factory settings, without using any backup data afterwards. Set up the rest of the personal settings manually and test the music app.

If the phone works as before the update, restore from the latest backup. If the problem comes back, the backup data contained corrupt data, causing your issues.

Your post is a month old, but the other reply wasn't very good. See this thread: Music apps crashing after the ios 8.3 update

Looks like lots of others have the problem too, myself as well.

I found its the smart Playlist if your running ios 8.3. I didnt have this problem in 8.2. I tried deleted them, and recreating the smart playlist. I found that the music will play normally without any problems (skip songs, fast forward, etc) if you dont have the smart playlist on your iphone. I tried re creating the smart playlist, and i get the same errors as all you guys reported. So its defiantly and IOS issue. I guess the short remedy is report it, and just delete the smart playlist and just play your regular play-listed songs.. Least until Apple comes out with an update to remedy the errors.
