If you are a Tangerine! user, please do NOT upgrade to QuickTime 7.2 yet.

If you do, you will not be able to analyze non-DRMed songs. Ironically, DRM protected songs are safe because QuickTime isn't used to get sound samples from them.

It seems like Tangerine! isn't the only thing affected by QuickTime 7.2 either as you can see here, here, and here. That last link has instructions on how to downgrade to QuickTime 7.1.6 if you already upgraded and can't live without Tangerine! for a week or two.

I am getting really tired of having my blood pressure shoot up whenever there's a system software update. I thought the last two iTunes updates were bad, but this seems like the worst yet.
