I use a program called Audacity to record audio tracks. My question comes in two parts for this particular program.

1. I'm wanting to record a song with my vocals and the proper background music. Can this be done with this program, and if so, how would I go about doing it?

2. I'm also curious to know if there is a website where I could find just background music (no vocals included) for several songs.

Any assistance that can be provided to me is most appreciated. Thank you.
