74 minutes WAS the original design limit (apparently because the designer wanted to put his favourite Mozart symphony on one!), but 80 minute CDs have been around for ages - both as commercial 'glass mastered' and as burnables. I haven't bought 74 minute blanks for years!

My portable CD player plays MP3 CDs, too - and I can usually put in excess of 180 tracks on a CD, roughly equivalent to 10 audio CDs.
