Yes Audacity can be used but there's a better way than answer one.

Note that the music tracks will need to be in wav, mp3, Ogg or aiff format. If not they will need to be converted or Audacity wont play them.

You'll need to specify recording in multi-track format.

Version 1.2 go to File menu, version 1.3 go to Edit menu / Preferences / Audio I/O tab and tick the "play other tracks while recording new one" box.

Open a backing track, click the record button and record your vocal on a new track. It's best to use headphones to monitor the backing track.

Try to record your vocal as loud as possible but without distortion to keep it "clean". The levels can be adjusted before saving as a final mix.
