When you hit PLAY, Songtrip will open the playlist in the program associated with M3U file format.
If the playlists are opening with some other player instead of your preferred one, you just have to set it as the default program to open M3U files in your computer.
You can do that by following these steps:
- On the Start menu, select Settings > Apps > Default apps.
- Scroll down til the bottom and select Choose default apps by file type.
- Type M3U on the search box.
- The default M3U player will be shown, just click on it and set it to your preferred player. Take attention to click on M3U, not M3U8.
