Edit the **** out of your music.

If you need to clean up language in your music, you can do it yourself for free using a music editing program. Zumba.com has recommended two free options for Zumba in the Circuit instructors. See more info here: http://www.zumba.com/en-US/zumbainthecircuit-tutorial/

Do NOT download Audacity using the link on that page because it's not the newest version. Instead, download the latest version here: http://audacity.sourceforge.net/download/ I had trouble editing my music with the old version until I upgraded to a newer one.

Once you install Audacity, open the program and go to File > Import > Audio. Choose the song you want to edit. Click the green play button and listen to the song until you hear the offensive section. Using the View menu, zoom into the section that you want to modify. Highlight the section of the song and click the play button, zooming and highlighting until you are highlighting the exact part that needs to be changed. Under the Effect menu, choose "Reverse".  Highlight a larger section of the song and listen to that phrase with the updated audio. If it doesn't cover up the lyrics enough, you can try some of the other Effects. Click File > Export to save the new song as an mp3.

Or watch this video I found that explains those steps: http://www.youtube.com/watch?v=Zy3JrZHJrX4
