Mix2Stix fills your mp3 player with random files.
Version 1 of Mix2Stix is doing its job just great, get it at https://mix2stix.de.
The code is hosted at Codeberg: https://codeberg.org/azett/Mix2Stix_v1
But its author built it maaany years ago, the code quality is rather poor. So this project here is planned to become version 2 of Mix2Stix. It will be coded from scratch, with proper code quality and much more possibilities to be extended.
