A Lot of problems

1) with 40000 songs are really slow! There is no cache!
2) when you download music in local you cannot see which songs are downloading
3) you cannot search a song just in your library!
4) when add a song to one drive, need 1 day for see this song! The sync inside to the settings not work!
