When playing music, if the track switches while the screen is off the title and artist does not update to the current song when the screen is turned back on. The only solution to get it to refresh is to turn the screen on, then off, then back on and it will be updated. Pretty sure this is a common issue because it happens on all of my AOSP flavored devices (stock nexus 5 & 7 it happened on, after installing CM on both of them it still happens, used to happen on my S3 with CM, PA, AOKP, and PAC). I've searched the forums here and didn't see anything (although it's difficult to search without getting tons of results related to the actual media apps not updating libraries or lockscreen weather not updating). Oddly enough, the album art does update to the correct art, it's just the text that doesn't refresh. Does anyone else experience this/know a solution?
