I can't burn a mp3 file lasting over 80 min. on an 80 min. CD.  It's been done however and I can't figure out how he did it.  He burned 1:25min on an 80 min. CD.
How can I do this.?

Hi

There is overburn capable software available like Nero but it Will not allow 1:25 to be burned on 80min.
The concept is, audio files are measured in kbps and minutes.

Data cds are measured in megabytes, so you can burn a mp3 file that plays for 1:25 on a 700mb disk as long as the DATA file is no bigger then 700mb (give or take a few Mb)

Most modern CD players (portables and car players, and possibly some computer units too) now play MP3 as a native format when burned as a data CD.

So it is entirely possible to burn a data CD with several hours of MP3 files on it and have a portable or car player to play it as though it were a music CD.  This might be the situation you encountered.
No sense in me typing out any further explanations when it has already been explained, so just treat my previous comments as supplementary information:

"Audio CD" format: The total play time of all the source audio files to be burned to CD is the restriction.
"Data CD" or "MP3 CD" format;  The combined file size of all files to be burned to CD is the restriction.

MP3 files can be encoded at different "bit rates, which is a rough guide to the "quality".  In general the higher the bit rate, the greater the file size of the MP3 file.  96 to 128 kbps (kilobytes per second) is less than "CD quality".  128, 160, 192 kbps is something like "Good" or CD Quality.   256 and 320 kbps is high quality.  These are just very rough guides though.  Of course, determining the difference in quality depends on what the music is being played back from, and encoding poor quality mono voice to an MP3 at 320 kbps is not worth it because it won't improve the quality of the original audio anyway.  Most people rip or record MP3s at 256 or 320 kbps these days because larger hard drives mean we don't have to worry about using up storage space, but they probably wouldn't be able to discern a difference in quality if they encoded at 192 kbps.
