Rdio Help Center

Playback / pre buffer - seemless track playback.

It's really annoying to have a piece of music pause for a half second as one track moves into another. This is especially common with intro tracks, or classical and orchestrated arrangements. Clearly, it cant be impossible for Rdio to pre-choose whats next based on continuous playback, buffer it slightly before the current track ends and the next one is to begin and then connect it so that the transition from one track to another is seamless.

I hope to see this feature, and I think it's the kind of small touch that would really help improve Rdio.
oh and off topic: "The White Rdio design still sucks a lot"
