Derek Kessler reporting for PreCentral:

the TouchPad will come with a music syncing solution built-in that utilizes cloud servers to sync and remotely store your music. More than that, it will leverage a “smart algorithm” to ensure that the music the user is most likely to listen to is cached locally on the device. This service will also allow TouchPad owners to stream music that they don’t yet own. There’s also mention that this service will allow you to stream music to HP smartphones, presumably once they too are updated to webOS 3.0 like the TouchPad.
