Rdio, the subscription-based social music service, today announced the addition of its Rdio app to the Verizon V Cast Apps storefront. Available only to customers with select Android devices, the app is one of the first in Verizon's app store to offer subscriptions via direct carrier billing.

While the service remains the same, the new option to lump your monthly subscription fee in with your Verizon Wireless bill is sure to entice at least a handful of new subscribers. "Our new relationship with Verizon Wireless makes the Rdio social music experience available to millions of mobile subscribers and simple to pay for through direct carrier billing," said Drew Larner, CEO of Rdio. Considering the growing competition in the social music space, lowering the barrier of entry into their service is certainly a smooth move.

For those interested, just download Rdio from the V Cast Apps store to get a seven-day free trial. After that, you can elect to subscribe to Rdio Unlimited for $9.99 per month. And parents, you might want to pay extra careful attention to your music-loving children's wireless bills.
