SonicSwap for Mac

From KeyMedia:

Ever wish you could transform your iTunes playlists into personal music video playlists you could watch, post, and share with friends anywhere? Now you can. This hot iTunes accessory brings a whole new dimension to your music collection. Use this free plug-in to upload your playlists to a personal account on SonicSwap where they are automatically converted into video playlists of live concert recordings and original music videos.

This also gives you hot key control, quick views of what's playing, and easy ways to tag your tracks. Want to buy a track to load on your iPod...a quick click links you to the iTunes Music Store.

SonicSwap's Shop Smart feature helps you find the tracks you need to complete your collection of your favorite artist's tracks. It automatically compares your track library against an artist's discography or a playlist to show you the tracks you need, and keep you from buying what you already have.
