They're supposed to be selling particular products. Instead they're selling me on new music! I'm sort of infatuated with the songs in these commercials:
("1234" by Feist)
("The Way I Am" by Ingrid Michaelson)
And I love the most current JC Penny commercial. This isn't the commercial (I can't find it online) but it's the song, live, performed by the artist herself.
("Music Box" by Regina Spektor)
I think I'm on a very noticable quirky-female-singer-songwriter kick.
