Well many software will do you that and almost every new media player software can do that for you.

If you will use Nero, just check for Audio and under that you will find many options. Choose the Create Audio CD and then you will see that the free and full space on the CD would be calculated in terms of minutes [Max. 80 Min in most of them] instead of MBs [Max. 700 MB].

That is the first indicator that you are on the right track. The second would be [depending on the length of each song and it's quality, let's say 4.0 MB per song] the total number of songs would be between [18 - 22 songs]. If the CD will accept something like 100 or 200 songs there, then you are making a Data or MP3 CD ...

After that burn those, and then enjoy listening to your music ...
