I'm a bit late to this but....

I went on to Amazon music one day and it said that now to add songs you have to "like" them so now all the songs I had in my music library by simply clicking the plus to "add to music" is gone. It was not added to a playlist it was just added to my music. I still have my downloads and previous "likes" but is there a way for me to get my music back? Please help, I had a lot of songs and I don't have them in my music anymore.
