I've thought about this for a while, now, and I think I've finally decided on the top three cheesiest songs used in TV commercials:
1. "Taking Care of Business" by Bachman-Turner Overdrive
2. "More Than A Feeling" by Boston
3. "Bad to the Bone" by George Thorogood & The Destroyers
Any company that plays one of these songs as the soundtrack for its commercial is calling you an idiot, so don't by their stuff.
