The company says that the new offer is “specifically designed to appeal to people with ears and hearts.” Users will simply need to sign up to access the free streaming features without the need for a credit card. A meter at the top of user profile pages lets people know how much free music they have remaining each month. Once the 6-month trial expires, subscription starts at $4.99 a month. There’s also a Rdio Unlimited option for unlimited web and mobile streaming which is priced at $9.99 a month. Rdio offers over 18 million songs, customizable playlists, and Facebook and Twitter integration.
