In Japan, commercials for products are also used to launch music careers. Touting that a song was featured in a particular commercial is not anathema.
I don’t know if the Liberty Mutual ad will have people running for Hem’s albums, but I hope it gets people curious.
Hearing Hem on an ad made me feel the same way when Applied Material featured Onitsuka Chihiro’s "Innocense" in an ad many years back — it was like I’m an insider or something.
To put it less charitably, it made me feel cooler than the rest of you.
