Bridge Nine Records has unveiled a new flat-rate digital music streaming service. The label is charging $4/month or $30/year for streaming-only access to the labels entire back catalog. The service will run through the label's social service/message boards at theB9.com

The idea of an all-you-can-eat streaming service has been attempted with some success by music stores like Microsoft's Zune, Napster and Rhapsody. Other sites like the much-hyped Rdio provide a streaming service in a radio playlist format and Spotify, which promises ad-supported streaming, is expected to launch in the US soon.
