You missed one.....

We have had thousands of people create portable playlists since we launched this feature a month ago or so.

Big difference in our technology, we enable quick/rapid blogging or publishing of your playlists, the blog widget that can be published to all the major platforms includes audio-clips and album art.

I'm suprised their arent more online music labels that could promote less well known bands - sure web2.0 helps promote unsigned bands via social networking but as a business why does a record label need music shops and cds anymore.

You may find there are more of these labels than you realise - but, by definition, they are not very well known themselves. Cases like Magnature, Artists Without A Label, SliceThePie, and so on. Then, because they are creatively reconstructing what it means to be a label, some of them don't look like labels e.g. Amie Street, which you could argue is not a label, but does help promote less well known bands through its model.

The fact is, no one has yet got rich and famous by promoting less well known bands using Web 2.0 models.
