There’s an instant mix option in emby music library but I can’t find this or a similar functionality in yatse at the moment. Sorry if it’s already been implemented or has been discussed before, but haven’t been able to find it yet.
It seems that the instant mix feature in emby is a bit more complex than I initially thought, and it probably uses more attributes in a ‘smart’ way to create a playlist than simply ‘genre’. Better "QUICK MIX" or SMART PLAYLIST option, like Pandora, or LASTFM - Feature Requests - Emby Community
That’s all I could find…
