Hey Guys, i just read the comments and saw you have the "This is a pirated version of Deezer" problem. I can tell you a trick to avoid this problem but not fully.
1.Open Deezer
2.Search for music what you like
3.Then play the "This is pirated version of Deezer" "Song"
4.When the play tab appears, tap to Playlist button and MAGIC!!
5.You can see the search results in the playlist and you can play and save them.
(When you save offline the song/songs the "This is Pirated version of Deezer" song from your offline music library temporarily disappears and your songs appear until you are in Offline mode)
