Spotify seems busy. Various sources say the on-demand (and custom radio) music streamer will soon launch a browswer-based version of the service. In other words, instead of downloading and installing Spotify on your desktop, you'll simply be able to listen via Chrome or IE or Safari at Spotify.com (like you'd listen to Pandora or AccuRadio), which will make it easier to use the service from multiple computers (and make it easier for potential listeners to sample it -- no download/install necessary). TechCrunch has more here, AllThingsDigital here. What other reasons might Spotify have for putting its service on the web? Evolver.fm has some ideas here.
What's more, TechCrunch here has also picked up the idea that Spotify may push its "App Center" (the section of the desktop software where you can find cool third-party uses of Spotify) to its mobile app (there's currently no link to the App Center on mobile devices). Last week Hypebot.com reported here on Spotify's Android app update.
