According to Mobile Marketing News, BLACK SABBATH's "Iron Man" has risen to No. 5 in Billboard magazine's ringtone chart — fueled in no small part by the success of the "Iron Man" movie which features the song in its trailers and its closing credits.

"Iron Man" comes off the band's second album, "Paranoid", and only managed to climb halfway up the charts when released in 1972. Thirty six year later its ringtone version is proving far more popular.
