> Something I am still looking for: folder-based music player with a seek UI that works well for long audio files (for example fine-seeking in a 4 hour long mp3) I've been using "Smart AudioBook Player" by Alex Software (available via the play store). I particularly like the sleep timer, ability to change playback speed and the fact it seems to cope with extremely long audio files without having any problems.
