ReverbNation

What Company says:
"We bring together artists, fans, venues, and record labels to forge relationships around the music that sustains us. Even in the age of the internet, music is still enjoyed both live and recorded, and still travels from fan to fan. ReverbNation is here to provide the online environment in which those relationships can thrive".
New Features:
ReverbNation now has a new profile option just for marketing purposes. The new profiles are to be used by Record Labels and Management Companies for the promotion of all the artists on their label. ReverbNation offers tracking and metrics as well, so you can see how the online marketing is going.

Offered with these profiles are free FanReach email management tools, a way to set up an Artists Roster with their associated songs, a consolidated show schedule for all your artists, a New Releases area, a Street Team function for encouraging web users to help you spread the word, and a customizable widget for the promotion of your artists.
This widget offering is TuneWidget, which ReverbNation launched about a month ago. It includes a cross-promotional tool that lets you display a recommended artist at the bottom of the widget. This plays into the whole new profile that ReverbNation is now releasing now.
