Both MediaMonkey and MusicBee, as music players let you 'rate' songs from 1 to 5 stars. I would like to have this functionality as well in an Android app. The main problem is syncing these ratings. Android apps like NRG Player do have a rating, however if I rate songs using NRG Player, they are not 'understood' by neither MediaMonkey nor MusicBee. Also, any ratings I give to songs via MediaMonkey or MusicBee are neither understood by the NRG Player.
Is there any app which reads/writes ratings in the same format that either MediaMonkey or MusicBee do? Or any app which syncs such ratings?
