I often have the urge to play a non-lyrical melody in the background, with its own volume meter, and then also start a completely different song with lyrics and have it on as the main background music.
Essentially, I wish I could have multiple songs playing at once in foobar2000. Is this perhaps possible already?
I have not noticed any way to start multiple instances of foobar2000 to achieve this, but even if that can be done, it doesn't sound optimal for many reasons.
