I currently use finamp (on phone), volumio (for home speakers).
I wanted to know if plugin either server side or client side exist which can play songs automatically based on first song played?
I want to be able to select a song and play similar songs instead of manually creating playlist and updating them when new content is added.
[EDIT] : very early impressions (using both symfonium and Finamp).
Both of them can't jump languages (English, Arabic, Hindi)
I prefer Finamp track mix for Hindi songs (album contains multiple genre and artists). It seems to play similar sounding songs easily.
Actually read about it in the past but couldn't purchase since I don't use Google services. But now I see Kofi donation option so definitely giving it a try.
This may not be what you want but I use Feishin client on my desktop, and it has button to play random songs. I just click it, select a range of release year and then select the number of songs I want. It automatically creates a temporary playlist. I think it also has a genre selection, so this might help you.
