Overall I agree with a lot of what you said.
Best vocal I heard was Loren it wasn't even close. Although I give honorable mentions to Daniel, Michael, Nick and Clark. A few others I thought were solid as well.
Katherine, thankfully they didn't put her through, she destroyed one of my many favorite songs. I had to lower the volume, that was by far the weakest in my opinion.
Other notes: Adam in my opinion should of got through, only one I felt that should of went through that didn't. I don't share your positive opinion on Maddie and Quentin as I didn't love either, but the judges liked them and so did you. so there's that. Anyways that is basically all I got to say. Next week we get to the top 24. Looking foward to it in my opinion, as at least we are now starting to get rid of alot of the weaker singers at least in my opinion. All is just my opinion, and I could always be wrong though.
