I have to post this song, because I watched tennis obsessively during the U.S. Open and during practically ever commercial outro they would play a few bars of this song. And I knew that I knew it, but I had no idea what it was.
It's Smallpools, from that Daily Candy summer playlist! The singer's voice is a little punk-pop emo, but it is definitely an ear worm. Apparently the band just played their first show this summer, so maybe US Open syndication money is big money for them. Will radio be next?
