I was messing around with tagging in Itunes yesterday, and decided to figure out how much music I have from each decade. (Of course, Classical music is going to fall all over the place since it is usually dated when it was recorded.)
Total time: 31.5 days.
50's: 2.7 hours.
6o's 1.6 days.
70's 1.6 days.
80's 2.7 days.
90's 5.7 days.
oo's 16.8 days.
10's 3.2 days.
Apparently I need more 50's music.
