Download a program that can burn CDs, like iTunes (for Mac and PC) or Windows Media Player (for PC only); iTunes is available for free from Apple's website, and Windows Media Player is available for free from Microsoft's website.
Create a playlist of the songs you want on your CD. This can be done in iTunes by selecting "File" and "New Playlist," and then by adding songs to the playlist from your library. In Windows Media Player, you must select "Library," then "Playlists," then "Create Playlist," before you can add the desired songs.
Burn your CD in iTunes if this is your chosen program. Select "Burn Disc." A menu will pop up with your disc options. Check the box that says "Use Sound Check." After the other specifications are to your satisfaction, burn the disc.
Burn the CD in Windows Media Player, if this is the program you are using. Select "Tools," then "Options." Under the "Devices" tab, select the drive you are using with the CD, usually Drive D or higher. Under "Properties," select "Quality," then choose to "Apply volume leveling to music when it is burned." Then select "Start Burn" to record your CD.
