Let's face it. A lot of news music is getting severely dated. Synths were all fine and dandy in the 90's, but put pretty much any package that wasn't made recently next to, I don't know, Strive, and listen to the difference. I know which one I'd put on a station I was in charge of. Outside of this board, literally nobody cares what music is being used and you'd be hard pressed to find many people at a television station that even knows what their music package is called, let alone who composed it. There might be a nutty CSD or GM somewhere that insists on keeping those cuts of MCTYW alive out of tradition, but there will come a time when even those are retired (probably after said people do the same).
The old version of the music was getting dated. It was worn out. It didn't match the fresh new look of the new graphics. This version of Stimulus is very likely middle ground between someone at the station who wanted something exciting and new and someone who was insisting the old theme stay around because of some buzzwords like Brand Association or something equally as absurd. It could have gone away entirely. You could be watching ABC7 Eyewitness News with Indie Band News playing over the open.
Everyone could still be using Teletype sounds as the bed to their news open, but they don't because better things came along.
