Amazon Marketed #Superbowl Songs Via Twitter

iTunes may dominate the digital music market, but time and time again Amazon has proven that they're willing to hustle.

The Super Bowl is a perfect example of this and the company's efforts deserve praise.

For every song that aired in a commercial, Amazon MP3 tweeted links to where budding fans could purchase the tracks.

It's a subtle gesture, but an important lesson. iTunes might sell music. But Amazon takes initiative and markets it too. And that's a big difference.
