I've definitely heard this on the radio, because that's the only place I would have heard it since I don't have any of their albums and none of my friends do either. I'm not a huge AC/DC fan, but they rock pretty consistently, and this song is no exception. Also, there aren't many songs praising the big ladies, but it's kinda cool that there are some, and they're sincere. No tongue-in-check double entendres. She's big, but she's awesome. Anyone who has a problem with that, well, it's their problem.
