Apple added "iTunes Plus" in May 2007, the $1.29 DRM free, 256 kbit format as an alternative to the $0.99, 128 kbit DRM format. Only EMI signed on (along with a few independents later). October of 07, the price dropped to the same $0.99 for Plus songs. January 09 was when everything switched to iTunes Plus, after Universal Music Group, Sony BMG and Warner Music Group agreed. That was also when the labels had agreed to let their music be downloaded over 3G to iPhones. Up till then, it was WiFi only. So not only do the labels control a lot of the pricing, they also control the little details of what network their music can be downloaded over.
