MUSIC APPS: 'SOUNDTRACKING' AND 'SUPERGLUED'

Long before social check-in location service Foursquare recently disclosed that it has a very respectable 7.5 million user accounts, the question over the service's utility for the music industry has lingered.

During his MidemNet keynote appearance in January, Foursquare co-founder Naveen Selvadurai ducked a question about how artists can best use the service. And after Foursquare released an update to its service at South by Southwest (SXSW), head of product Alex Rainert was asked how the new version would affect music fans. He gave an answer about finding better sushi.
