Snocap, the creator of the music-selling widget, has launched a Pandora mashup enabling you to find and purchase downloads as your Pandora radio station streams.
This combined service is an interesting mashup that offers the best of both of these music worlds. As your music plays on Pandora, Snocap will automatically search all of the artists and songs that match the current artist playing. You can then browse through the Snocap results in order to add songs to your cart for purchase. The Snocap store window can be opened in another window as well. You'll have to move quickly, though, as the Snocap store changes with your streaming Pandora music. If you open the Snocap store in a separate window, though, it will not change along with your next Pandora song.
eMusic has also launched a Pandora mashup, which allows you to download any available music while simultaneously listening to your favorite streaming music as well.
