Music app won't play any newly downloaded songs
New music won't show in Library, nor it can be played by the Music app. If I double click on a song, it opens Music app but just blinks white square and nothing happens. The only songs that play are the old ones that are already in the Library. Interesting is that newly downloaded music videos do appear in the Music app. Mp3 however do not show or play anymore.
