how

Answer 1

Try this:

Change the speed of your music

Music players like Windows Media Player aren't designed for sound editing. But there are plenty of sound editing programs that can handle what you need. I recommend Audacity, which is free. You can find it through the Downloads section of my site.
Before editing, you'll have to get the song off the CD and onto your computer. You can do that with Media Player. In Media Player, click Tools>>Options. Select the Rip Music tab.
Under Format, select WAV. Click OK. Then insert your CD and select Rip on the main menu. Make sure the song you want is selected and click Rip Music. The resulting WAV file will allow for editing in Audacity.
Audacity can speed up a song in either of two methods. One is in the traditional method, as you might speed up a record or tape. But this can create problems if the music is a backdrop for your voice.
As many people know by experience, a song played faster tends to sound high-pitched. Vocals approach the sounds of Alvin and the Chipmunks. Instrumentals also sound higher, which means you'll have to sing in a different key.
To avoid these problems, Audacity also features time stretching. Time stretching speeds or slows the tempo without changing the pitch. It's akin to a live band playing faster. Every quality but the tempo remains unchanged.

For time stretching, click Effects>>Change Tempo. You can enter a percentage for the change.
If you prefer a traditional speedup, click Effects>>Change Speed. A percentage change can be entered here, too.
After you get to the speed you want, save the song. Then burn it to CD using your normal CD burning software. Just about all software will be able to turn WAV into CD audio. If you need a CD-burning program, check my Downloads page.
