I've just noticed a rather interesting pattern regarding TWC artists published by supermax music and their BMI work numbers. If I, for example, take the work number (8705127) for "Just We Two" by Kim Hansen (featured in March 2007) and I search for 8705126, I get "Above the Horizon" by Sam Lincoln, which was also featured in the March playlist. As I continue going down, here are the results:
8705125 - Tender Moment by Tony Davilio
8705124 - Hip Hop by Patrick Yandall
Once I reach a song that's not on the TWC playlist, I go up from the original number, and I get:
8705129 - Pressing On by Yvonne Ayers
8705130 - Across the Bay by Donna Kilpatrick
8705131 - On the Bayou by Patrick Yandall
etc...
All those songs I listed were in the March playlist. Knowing this, we could possibly figure out some of the songs that were in the February 2007 and April 2007 playlists.
