Play MiniTunes is a iTunes quick song player and controller.
It has two functions. One is the song "search-and-play" in which you type the song or artist name, hit the return key and presto your song starts playing! If more than one song matches the criteria, all matches are displayed and you make pick which one you want to play. If you do the artist search, all songs by that particular artist is brought up. The second half is a nice and easy controller where it displays the track info, plus fast forward/next track, play/pause, rewind/back track, mute on/off and volume control. There is a button that will show a panel with the current song's album artwork as well.
Also in the application menu you are able to open the iTunes prefs, and use shuffle, repeat, rank current song out of 5 stars, set genre and more.
