I can not reproduce the reboot thing on MMS or Music.
To people that have:
1. Did you do a clear of cache and dalvik and also format /system before install the new ROM?
2. Where are you playing music from, I tried from lock screen and from the app?
3. I dont have any album info, the image is just a blank CD looking image, is that what you see or was the issue when you DO HAVE album images?
4. MMS issue, did you clear data for MMS app?
Im thinking of just making flashable zips for MMS seperate and Music seperate if the issues still exist.
