I will give you my take on this
Fabio has been extremely busy and it just wasn't a high priority item and we were already running late enough with 5.0 release. It got brought up, but we just didn't keep focus on it as we had more pressing issues and with the clock ticking, well you can guess the rest of the story.
I was all for a change of song, we will have to push for it in 5.1 - maybe a new topic where the community can post their suggestions and it would make it easier for us to pick one instead of trying to hunt something down ourselves when trying to get other things done. Everyone can benefit from it as music is good for the soul I say.
