Sanfran should have been in the top 3
They sounded as good as any of the top three. Traces had a decent sound, but low as their "bass" chick could get, they were still lacking a good firm bottom that I just have to hear in a song. And their I'm Every Woman arrangement didn't do it for me, the fast part mainly. I liked the intro to it, but I just wasn't feeling the beat in the fast part and it just wasn't hittin' and and the harmonies didn't lock in, IMO. And I think I just didn't really like the Tina Turner song. I need to listen to the original, which I've never heard, and hear the ladies again. I didn't know that Ariana Grande song, either (and a couple months ago I didn't even know who Ariana Grande was), but I liked what they sang right off.
And that A Squared group performance sounded good, but they need to get off of The Sing-Off with that electronic stuff. The only thing electronic should be the mikes and minimal production/engineering stuff, IMO.
