This affects all digital stores. Many labels appear to have lost their uncompressed masters, especially for stuff that was released on the internet in the early 2000s. I regularly catch them pants down when trying to buy something through digital music stores as lossless and I receive a FLAC file that shows clear signs of MP3 compression. It usually results in a refund from the store in question. For this reason I'm buying less and less through those stores, and try to hunt down cheap used CD copies instead, if at all possible.
