Duke Listens!: Visit my main blog at MusicMachinery.com

Mog is a social music site, still in private beta.  It looks like it will be similar to  MySpace with a heavy music influence, as well as some automated recommender and user-to-user affinity matching. 

The social music discovery space is starting to get quite crowded.  Let's see how many we can name:

• last.fm
• MusicMobs
• MusicStrands
• Mercora
• WebJay
• ccMixterSoundFlavor
• upTo11.net
• plurn
  
• GenieLab
• Jamendo
• Muiso
• internet iTunes Registry
• Gnoosic
• SoundFlavor
• Gnoosic

That's quite a list.  The social side of things is starting to get a bit crowded, but it seems that everyone of these services brings something unique to the table.
