I am looking for an Android application having the following features:
- Can play MP3s
- Can assign labels to MP3s: ideally we could choose in which ID3 field they should be saved, or that could be exported easily (e.g. in a CVS with fields: MP3 filename, label). Still ideally, the user should be able to create labels. Labels are strings, e.g. "house".
- Can list all MP3s that have been assigned to a given label
- Allows to navigate to any directory and play all tracks located in this directory (like the app Folder Player)
- Can assign several labels to one track
- Can play FLACs as well
- Is free
