Today is a big day in the iTunes Store, as Apple implemented some changes initially announced a few months ago. Whereas all songs had been 99¢, now some are 69¢ while the latest tunes are now typically more expensive at $1.29. Also Apple has removed the DRM (digital rights management) scheme the limits the number of devices that can play music you purchased. You can now convert purchased music to your preferred format and put it on as many devices and computers as you like. Yahoo Tech has a great article that explains the details of the developments, including how to convert music to your preferred format and an explanation of why it's no longer necessary to pay for ringtones in the iTunes Store. The article also notes that not all of the music available in the store has made the transition to being DRM-free.
