Not only puts you to sleep and wakes you up, but does the same for your Mac. This app plays the music of your choice as you fall asleep, then puts your Mac to sleep at the time you designate. Later, it can wake your Mac and play another song (or radio station) to wake you up. There’s even a snooze button.
Compare your iTunes library with a friend’s and see which songs you don’t have in common. Or use it to make sure your own libraries are in sync. Also helps with making sure a migration goes well.

Find and add missing lyrics to songs in your music library. Won’t overwrite current lyrics. Drag and drop tracks from your favorite music player (e.g. iTunes) and the app does the rest.
