Yesterday's post about the Boxee bookmarklet got me thinking about other bookmarklets I love. The first one that popped into my head: GrooveSelect.

Suppose a Facebook friend mentions a cool new song he just heard, but doesn't provide a link to it. (Courtesy, people!) No problem: just highlight the name of the song, then click the GrooveSelect bookmarklet.

In a minute or two, the song will start playing right in your browser, no software, plug-ins, or sign-ups required. You can even continue browsing, though if you close or leave the current tab, the song will get interrupted.

As you may have guessed from the name, GrooveSelect pulls from the way-cool Grooveshark service. It's the ultimate answer to those times when you see the name of a song and think, "I sure would like to listen to that."

If that song appears as text in your browser (preferably with the artist's name alongside it), just highlight and click. How awesome is that?

Once you've added the GrooveSelect bookmarklet to your favorites toolbar, give it a try with this tune, one of my favorites: Brendan Benson - My Old, Familiar Friend.
