Minna no uta is a daily NHK program that's been running since 1961. The show (which is only five minutes long) rotates several songs each month. Sometimes, the songs take on lives of their own. One was done by Lou Oshiba, MOTTAINAI ～もったいない～ (thanks to youtube user dora1122):
Oshiba is hoping to sing this song at the Red and White Songfest.
One of last month's songs was おしりかじり虫 (Oshirikajirimushi) which is the bug that bites bottoms. It's a bit...strange.
