Mp3 Music Player is a music player that besides offering a more than noteworthy playback quality also lets you keep a nicely organized library of digital tracks.
The main problem with Mp3 Music Player is that it doesn't automatically detect your audio files, meaning you'll have to open them one by one. Once you get through this process you can start enjoying its features: filtering tracks by artist, album, or title; an equalizer to adjust the sound to your taste; and interesting, albeit limited, customization options for the interface.
Mp3 Music Player solely plays music in .MP3 format so although it won't help you organize your WhatsApp audio tracks, it will indeed play most of the tracks in your music library with no problem.
