A flirty and seasonal classic, or an out-dated song that's problematic?

It's a debate that's reignited every year as the calendars flip to November and the temperatures grow frostier: Is "Baby, It's Cold Outside" good, or bad?

The fight over the song heated up in Denver when KOSI, a radio station that plays exclusively holiday tunes this time of year, banned the song, only to quickly bring it back.  Interestingly enough, the song itself may now be a holiday classic, but it's not actually a holiday song.

Bret Saunders, a longtime KBCO radio host and jazz columnist for The Denver Post, talked to Colorado Matters about the debate over "Baby, It's Cold Outside" and other songs that have aged poorly.
