RBN needs 'official' release announcements.
Sites like joystiq put out weekly 'new songs on Rock band' postings, and it is a shame (crime!) that they don't include RBN songs.
I assume sites like this rely on official announcements. I know RBN songs are released in a stranger way, but that can be dealt with.
Even if the 'official' announcents are 2 weeks behind (ie songs posted two weeks ago), that's okay. The important thing is that the songs, and RBN itself get some deserved publicity.
