You’d be hard pressed to find someone who tries the online streaming radio service Pandora that doesn’t like it. In fact, some users like it so much that they actually ask for ways to pay the company, to make sure it stays alive (something that has been a question mark given the oppressive Internet radio licensing costs). And while there has been a limited subscription version for some time, Pandora has never proactively promoted it. But starting tomorrow it’s taking the freemium model seriously, with the launch of Pandora One.

The most obvious feature of Pandora One is the removal of ads from the site (this was the only feature of the previous subscription version) — that means not only the ads on the page but the in-stream audio ads as well. And there are five other keys to Pandora One that you get with your $36-a-year subscription price: The biggest one is access to a very solid Pandora desktop app. The others include high quality streaming, a personalized look, a mini player and extended player timeouts.
