Today I am trying to burn multiple mp3's to a single disc.
However, I did noticed that it required two disks to complete all 31 songs.
Therefore, I still attempt to burn it into 1 disc and yet it is no go.
Upon googling, I have found this --
Standard CDs only allow 74 minutes of play back time but most modern players will play back 80 minute ones also. These cds will allow 47 tracks but the songs would have to be very short. ie 80/47= 1m 42secs
