We've covered several apps that integrate with the social music platform Last.FM, and we've expressed our worries about what might happen to the site when it was bought by CBS. As it happens, though, Last.FM has only gotten better lately. And now that they've released a shiny new version of their public API, we're hoping for more development on the downloadable app front.

Here's the skinny on the new API features: there's now read/write authentication for desktop, web and mobile apps, which, besides being essential for any service that logs your music listening, sets the stage for -- dare we hope? -- a killer Last.fm app for iPhone. The API will also allow apps to access search functions and make playlists, which means easier access to Last.FM's growing library of free streaming tracks. Scrobble on, amigos.

UPDATE: Some of our astute readers have recommended MobileScrobbler as the killer Last.FM app for iPod/iPhone. Thanks, Neil and Robotrock.
