I have a problem with the filter, I'll give you an example because I dont know how to explain it.

If I have my playlist in alphabetical order (a-z) and I want a song of black sabbath, the filter works itself, the problem is that when I want to play that song, for some reason the first song is played (in this case it would be the of Bhonstro) and not the black sabbath`s song , it is as if the filter did not work. I do not know if I explain myself very well?. it happens with all my playlist. in the pc works good, but in the phone is when it goes bad, i already uninstall the app, log out, so i want your help please:) im from ecuador if it helps?
