Hijacking this thread on a tangential - can folks share some guides on the basics of getting started mixing music? For a total noob who would like to explore this field. Obviously those using open source software (or atleast software that works on Linux) would be the most useful to me.
You're looking for a DAW (digital audio workstation). Ardour is open source and works on Linux. It's not one of the "main" players but I'm sure it has all the important features. You can google "how to mix music" and apply pretty much any tutorial to any DAW.
