life of numbers

for my project i decided to use, my itunes/cd library. i used the top 9 played songs and then took those songs and found out what cd they were from and underneath used the cd release number from the record label , for example the first one is
144- times played
23- record release number ( the 23rd record the label put out) i then put them on to a midi keyboard adn played them various times, tunings, and used the pitch and modulation shift wheels to alter them in time. i liked this process and found it to be enjoyable.
her is my list:
144
23
120
