"When you're in a band and it's your passion, you've got to be careful about your catalog," says Velvet Revolver bassist and financial guru Duff McKagan. "When you license a song to a movie or T.V. show, you've gotta make sure that it's something that adds more validity to the song and not take away from it."

Country superstar Carrie Underwood is making headlines all over the world for outselling Mötley Crüe and their 1985 classic "Home Sweet Home." According to Nielsen SoundScan, Carrie's version has sold 211,000 digital copies to the Crüe's 181,000. None of this surprises McKagan, who chalks some of Carrie's success up to the power of television and the popularity of country music. Underwood's "Home Sweet Home" is featured each week on 'American Idol,' one of the highest rated shows on television.

"We've been careful with the Guns n' Roses catalog and the Velvet Revolver catalog," McKagan explains, thoughtfully. "You know, "Slither" was used in a Victoria's Secret commercial and that's killer. The commercial was dark and sexy and that adds mystique to the song. In terms of Carrie Underwood... Mötley are smart guys. Nikki is a real smart business guy. They probably thought, "F*ck it, this is an old song of ours, let's make some money off of it."

In addition to playing in Velvet Revolver and Loaded, Duff McKagan is a financial writer for 'Seattle Weekly' and Playboy.com.
