User blog comment:Evans0305/Rapture Archives now has Rapture Radio/@comment-1500935-20110430095220/@comment-2250991-20110430231228

If you go to the same page, under "Listen to Rapture Radio", there's a User Manual, which if you go through page 7 of the manual, mentions the promotional campaign. as for more, the manual does mention that some of the copyright owners won't let the station broadcast some of the songs, which is why it's limiting. But I do hope there would be some more in there.
