I just received an update on my favorite 3rd party BlackBerry Music Player called FlipSide...
BlackBerry users can now get Last.fm auto-scrobbling support with FlipSide, which means that when a tune is listened to, the name of the song is sent to Last.fm and added to the listener's profile. FlipSide users may enable scrobbling of the music they play to get better recommendations and share recently played music with friends via blogs, MySpace or as forum signatures.
If you're not familiar with the term "scrobble" (I wasn't at first) you can check it out at Urban Dictionary - it seems Last.fm invented the term for their purposes... though there apparently are other uses of the word too - Definition #4 is a little bit umm... well... yeah, I'll let you visit the link and read for yourself.
And if you're not familiar with FlipSide, it's a very graphical and user-friendly media player for the BlackBerry (compatible with Pearls, 8800s and Curves) that you'll want to check out. One of the most popular features is the ability to "swoosh" through the full-color cover art of an entire music collection within seconds using your Berry's trackball. FlipSide downloads and displays each album's cover art and even links to FlipSide Extras to provide biographies of the artists, recommendations for similar artists and more. Flipside plays music in MP3, M4A and AAC formats, and also allows users to create their own playlist. You can learn more about FlipSide and download a trial copy by visiting FlipSide.fm.
