All my saved songs disapear

[Emilio1126]

Yesterday I downloaded all my songs , today in the morning when I was about to hear my music all of them disapear , the only one were the ones I passed from my cellphone , but when I play a playlist and a song that I know I saved it says it save , but it doesn't show me that in my songs tab
