Different strokes for different folks, I watched the entire Grammys and I REALLY enjoyed it. There is not one group or song that I heard that I will seek and play, but I enjoyed the entire show and the performances. I liked Beyoncé, Lady GaGa, Adele, Katy Perry and a lot of the rapper stuff. I would never play any of their music but I enjoyed watching the entire extravaganza. I thought it was fun.
Edit - I just sat down and put the Grammys' back on to just listen to the music performances without any of the presentations or speeches. I loved watching Adele, and then the Weekend and Daft Punk were fun to watch. Keith Urban and Carrie Underwood sounded amazing to me, more about the performance than the sound, but I really enjoyed it.
Ed Sheeran's performance was incredible. Live in front of millions he first recorded his background vocals then with foot pedals basically he records and mixes 6+ tracks in real time, without missing a note. He had a band playing with him, while he was wailing away on his guitar and singing as well and played key board when recording the original tracks.....try to do that in front of millions

Anyway, I think the performances were fun to watch.
New country singer Kelsea Ballerina Lukas Graham from Denmark were amazing to me. They merged two songs and "7 years old" being one of them, which I love and for me a pure magical performance.
Bruno Mars.....incredible performance. With his two back up singers it brings back the Temptations and the Four Tops.
When Mars did the Prince tribute and played crazy lead guitar, along with Morris Day and the Time.....It was a WOW.
Sturgill Simpson had a 40 piece orchestra with 20 horns playing behind him that were over the top good.
I also enjoy seeing guys like Neil Diamond, Barry Gibb, John Travolta.....just seeing how they age and what they are like now.....I enjoy it.
I am watching it on a 200" projection system with 26 separate drivers and and 26 Dacs and 26 amplifiers driving the Surround System.....it's pretty much like being there. I personally know that if I was watching on a regular 50" tv, I probably would not even have watched it. Whatever
I was amazed with 3.5 hours of live tv with MASSIVE sets and multi media production orchestration happening on live tv with millions of eyeballs and other than a few glitches, I was amazed at the production sets and the amount of them.
I also do about 80% of my listening to new music. Favorite listening is Angus and Julia Stone, any of their 4 albums. Also Agnes Obel, London Grammar, Ben Howard and a few more.
