I just downloaded this album from the iTMS, and look at what it's showing for the bitrates! I wonder if it's just my computer showing them incorrectly, or if this is what they actually are?
If those are indeed the true bitrates, this isn't the first time it's happened. If I remember correctly, there have been a couple of other songs from iTMS that were encoded at higher than 128 kbps. Nonetheless, that is a great find!
