PlayStation Portable owners will be prompted to update their firmware to v3.93 today, which expands support for Playstation Network titles and also adds 20 new internet radio stations.

The official Playstation blog reports that, users of the PSP Internet Radio feature will find 20 new internet radio players to enjoy. The new players are organized into more specific styles of music so that PSP users can easily find what they are looking for and listen to their favorite genres.

They also report that more than 50 percent of PSP users listen to music on their system, so the new expansion should please everyone, and of course any expansion for game support is also welcome.
