Coversutra 2.1.4 For Mac
CoverSutra lets you control iTunes from a floating window that appears over the active application whenever you push the F6 key. From this window you can view the album art, song title, artist, and album name for the current song, as well as your playback buttons. CoverSutra can be launched from an icon on the menu bar that shows information about the current song.
If you click the icon, you can use the iTunes search function. CoverSutra is also compatible with LastFM. It shows the album art for the current song on your desktop, and you can use various keyboard shortcuts to control playback without having to use your mouse.
