There are real halakhic problems with using trashy tunes. Nobody should be using Erev Shel Shoshanim, Yaalili, Benny Friedman, Eli Gerstner, etc. from the amud.
Once I was at a minyan where the very yeshivish-looking precentor used a MBD tune for Kel Adon. I had to give him a piece of my mind afterwards.
Traditional nusach and synagogue music, as preserved in Kol Rina v’Todah (the United Synagogue Blue Book) makes the shul experience sublime. Nowadays, you get a pedestrian experience in shul, which is uninspiring and fails to uplift the neshama.
I also fault many Hasidim and other venues for not having a qualified baal koreh who knows the proper ta’amei hamikra.
