DRM on MP3s

I downloaded Incubus' new album and I noticed that if I had Java turned off (like any sane person should) it would direct me to a zip file download. The zip file only had 15 songs. I asked support about it and they were aloof, obviously they and their devs had never turned off Java after the first non-deluxe album. The Java downloader is unnecessary but there is an interesting property. The files are different from the ones in the zip file. At first I was certain that it was DRM. But it's pretty difficult to put DRM in one bit. That is what is happening here.

The only thing I can think of is that they could have DRM'ed the zip file also and I am just seeing the session id incrementing. However, I think it is unlikely that they have DRM'ed the zip file. Does anyone have a copy of Incubus - Monuments and Melodies to test against?
