Twitter and music go hand-in-hand, according to a study from market-research firm The NDP Group, which found that Twitter users are more likely to buy music online, TechCrunch reported.

The study found that Twitter users purchased 77% more music, on average, than non-Twitter users, and that 33% of Twitter users purchased a CD in the past month and 34% paid for a digital download, versus 23% and 16%, respectively, by overall Web users.

NDP added that one-third of Twitter users listened to music on a social-networking site, 41% listened to online radio (versus 22% among all Web users) and 39% watched a music video online (versus 25% for all Web users).
