I'm sure it's all right there, in ALL CAPS, plain as day in the 40 Page EULA.
I could swear I signed up in like 97, but my user id is way higher than yours.
What about a lowish number AND a username with illegal characters?
The community at Hydrogenaudio has prepared a Public Listening Test for comparison of the most popular audio codecs (AAC, Vorbis, and Microsoft's WMA included) in a battle to see how they stand at compressing audio at 64kbps.
Many of the participants right now have expressed their surprise at being unable to determine which is the original and which is the compressed version of 18 samples covering a vast amount of musical styles.
The results of this test (and other that are conducted at Hydrogenaudio) will be used by the developers of the codecs to further improve the "transparency" and let this kind of test be even harder.
Everyone is invited to participate and show how good your listening is!"
