But there are some sorting problems getting in the way. Multi-disc album handling does not exist at all. Digging through 5-6CD compilations is not any fun Because everything is lumped together in one list, and the track artist is not displayed. Fine if you already know the record inside out, but not for anything new.
So, the blacklist feature (for hiding tracks you do not want to display) is unreliable. Obviously you want to use this for Mainly ringtones and audio messages did do not ever belong in a music player. With Shuttle +, you can blacklist the song but not the artist. This Means there are artists / albums listed in my library as 'Unknown Artist', 'Ringtones', 'Downloads', 'WhatsApp Audio' etc. even though the songs within them are blacklisted and hidden. The parent folder quietly stays in the view. This could be solved by Easily Either comprehensively Implementing the blacklist, or Allowing you to choose your music directory.
But Ultimately, my advice: use it anyway. Shuttle + is awesome and the developer deserves the users.
