John Personally, I prefer to play background music on Spotify, Apple Music, etc. I perform in a variety of venues to a variety of audiences and I need a wide range of background music in different styles. Plus, I would get bored if I had the same background music every night. I don't support the idea that the StageTraxx developer would waste his time on background music functionality, which is already available in other, specialized apps.
I understand your need I am in the same boat , but I look at it differently , background music is just that BACKGROUND, I also play different venues with different culture people requiring different language music , I have various playlists that cater for mixed language as well as different genres of songs with about 2 hours of length each, I do not create these playlists for my own pleasure they are there to do one simple job and that’s to be a filler to the audience at a level they can still talk to each other and mingle conformably , ST3 is perfect for that as each playlist has its own level set so I don’t have to stuff around searching the net and playing around with things unnecessarily when I need to get off stage I simply choose my next song to be in the appropriate background music playlist and when I am done I have two options MIX to the background songs and walk off the stage the levels are correct and appropriate music is playing also I don’t need to worry about song choices as already played songs will be missed automatically, when I get back on stage I simply choose my playlist and select the next song to where I last left the playlist , this also is easy cause all my done songs are highlighted I simply choose the next song and either XFADE to start or wait till the end of the background music song and off I go again, no internet connection involved that could cause problems or complicated Spotify control or gaps in audio.
When I do serious work on the latest computers I still don’t like using multiple software at the same time because the risk of things going wrong are much higher, this mentality is specially useful when on stage .
It just means I don’t have much trust in computer developers cause I understand how easy it is for something to go wrong ,, the new generation of people totally trust the technology and that’s fine, i don’t think I will trust it in my lifetime.
ST3 is much better for background music than other dedicated background music players in my opinion.
Good luck with it all I am sure you will find a solution.
