im not exactly sure what point you are attempting to make. i dont think we have a Bais HaMikdosh at the current time, it should be built again mehayra. i dont think the L’veyim sing anymore to accompany the Korbonos. i dont believe they play instruments anymore. although Shuls today are a tiny tiny hint of what the Bais HaMikdosh was, i think any parallels you wish to draw, must be drawn by bigger heads than you and me.
the Maharal, again im not sure what that has to do with anything i said
i know why i go to Shul, and it most definitely is not to hear a concert or any other type of entertainment, CvS.
there are plenty of Temples that do enjoy that, i have no argument against it.
