Stock Music Player Bugs

[josearmz10789]

Since the update the stock music player no longer shows the correct tags on the songs. Some do show the year but most say unknown and many do not show the songs number and are not in the correct order. This is frustrating as all the songs are now at random. Anyone has this problem or am I a lone ranger. I tried clearing the cache, but nothing and also tried a factory reset and nothing. I am using wma files as I have been using them for a while now and on my S4 I never had a problem. I believe it was the update to 5.1 but I may be wrong.
