""Future of Music (2010)" is a Mac OS X app that scans your iTunes library and computes the music you are not supposed to listen to anymore based on your preferences. It then helpfully deletes it from iTunes and your hard drive. Skips the recycle bin.

Just click the button and let it take care of your life."

"Syncopation from Sonzea provides a hands-free solution to keep your iTunes® music collection synchronized across multiple computers running Mac OS X." And this is what might make a Squeezebox practical chez nous.

"The spreadsheet has an older, wiser cousin, and it is called database."
