There is a lot of crappy worship music.....the "me me me" spirit of many modern "worship" is disgusting.
But, there is a great variety of amazing songs that just make you fall to the ground as well.
Not all old hymns are deep or solid either. Some are awful.
There is going to be bad with every age of music.
Make a joyful noise unto the Lord!
It never said it has to sound good . . .
