Offtopic: Adding new songs

When I download a new song on my PC, I'd like to be able to later listen to my "newly added songs" on the phone and then assign it to the playlists it should be in.

There is a list called "Recently Added" in PowerAmp. It's probably perfectly fine.

But I was not sure how exactly it works and it is likely not the same thing as "All songs you have not yet assigned to a playlist" so I wrote a python script. It takes all songs from UNASSIGNED_SONGS_DIR, moves them to PERMANENT_SONGS_DIR which has a name depending on the current month, and adds them to an m3u playlist file using relative paths.

Now I can listen to that playlist on the phone on shuffle and assign the songs to playlists. Once I want, I remove it from that unassigned playlist.

Update Unordered Songs

This script could run at cron. But for now I will just run it manually after downloading a few songs to the UNASSIGNED_SONGS_DIR.

# This file assumes you are running it directly. Because otherwise __file__ might not be set
# and in that case we can't get the file's directory
