iPod-wielding music fans have a new way to test their pop culture credentials from software firm Coolgorilla.

Coolgorilla aims to release a slew of applications for iPods and is offering its debut product, the Coolgorilla Rock & Pop quiz, as a free download from its website.

"Use your iPod and answer questions on Gorrilaz, U2, Metallica, Beyonce, The Beatles, The Whites Stripes, The Killers, Madonna and many, many more," the company says.

The company is offering to send a free video iPod to the fastest player to register their scores and game duration online.

Movie and hip-hop music quizzes are also in the pipeline as the company experiments with using the iPod as a "sonic gaming platform".
