Reached Pandora Monthly Limit

My iPod has been showing signs of dying so I decided to spend the week listening to Pandora. Today, I reached my monthly listening limit. For .99 cents I can continue listening for the month. For $36 I can sign-up as a subscription-based paid user for the whole year.

Will this new paid subscription business plan work for Pandora? They also are currently playing ads between songs too. How close is Pandora or for that matter, Internet radio in jeopardy of going under again?
