Audio CDs are time based. The maximum number of songs is 99. However, the actual number of songs that you can fit on a CD will depend on how long the songs are.
You are limited to 74 minutes of audio per recorded audio CD. If you have an 80 minute blank CD-R, you can record up to 80 minutes if your CD recorder drive supports it. (The actual time of an 80 minute CD is 79 minutes and 30 seconds of audio, though.)
To burn an 80 minute CD with MP3 CD Burner, make sure that your CD-recorder supports 80 minute audio CDs. Not all CD-recorders support 80 minute CDRs! If you are not sure, consult your CD-recorder"s documentation or visit the manufacturer"s website for help.
By default, the software will automatically sense the capacity of any blank media that you put into your cd recorder, so if you don't want to think about it, just put in a blank CD while you are creating your song list to burn. (Make sure that the CD size next to "Arrange Song List" is "Audio CD (Detect Size)"
Make sure that the drop down on the "Arrange Song List" is set to Audio CD (80 min)
