There’s a commercial for Amtrak that I liked at first. It had a catchy little tune. After repeated hearings I’m starting to hate it, but I liked it at first.
The commercial for retail chain “Zellers” used a song by the Be Good Tanyas called “The Littlest Birds”. Liked it so much I bought the album. And then two other albums.
I think that all of the They Might Be Giants-penned Dunkin’ Donuts commercial jingles have been outstanding, to the point where I almost want them to release an album of the songs once the ad campaign is over.
