Dearest 100 Hour Board,
What’s the name of the song and artist in Target’s new back to school commercial?
It looks like several of us have done quite a bit of sleuthing online and haven't found anything. I also talked to a couple people at Target guest relations. One of the friendly fellows came back with an answer beginning with "unfortunately," and the other one left me on hold for so long that the music stopped and five minutes later the call ended. He did say he was going to "exhaust all available sources" trying to find an answer for me, so I suppose that would take a while. He got my phone number at the beginning of the call, so if I ever hear back from him, I'll post a correction.
Unfortunately, I think this boils down to one of those "well, we tried" answers for which I'm very sorry. If it makes you feel any better, it looks like several other people had the same question as you based on the comments in the link you included.
