Swedish duo Cazzette have released their first album on the music streaming site and it isn't available to purchase or download.
Music streaming service hopes to bring in more users through its new incentives program.
While 73% of people listen to music through streaming players like Rdio, only 20% of them will pay for it.
Last quarter, the streaming music service accounted for 8% of the music group's total revenue.
Technology will allow for features like more advanced satellite-based navigation and stereos that work exclusively offer web-streaming music through smartphone controls.
A study indicated that the popular music streaming service discourages people from buying music.
