I call it "interlude" music. A few years back the organist was playing interlude music before Mass. One of the hits of the day was "The Impossible Dream"!
Our organist never cuts loose with Louis Vierne until the postlude . . . although if he played him up front, nobody could talk before Mass because they couldn't hear themselves think (which would kind of make it pointless because they couldn't hear themselves pray, either.)
Man of LaMancha? I hate to break it to you, but that was a LOT more than a few years back :^D
In my parish, it had devolved to 'lounge music', ala Bill Murray in some cheesy SNL lounge act skit, meant to make us laugh!, or some seedy, off the beaten track Vegas bar (I've never been to Vegas, relying on TV recreations). It is rambling, clangy, and mostly features non-religious musical choices. Our temporary pastor has banned them from playing 'that kind' of music as the after Eucharist meditation - so they quit in protest! For now at least. That same kind of defiant behavior the Cardinal spoke of. They also had permission to sing on the altar, which newer pastors had never challenged, and the girls in the group were known for their 'sleazy' outfits. I think Cardinal Arinze really nailed it. And our temporary pastor is on board, too.
