First, there's relatively little newly recorded content. Most of the content is just selections from the regular radio recordings. There is no guest for the DJCD recording.
Second, there is no data CD-ROM.
Third, audio quality is shockingly bad for a DJCD. I thought they can't really mess up non-music CDs, but they proved me wrong. It's not unbearably annoying like badly mastered music CDs, but I didn't expect DJCD to be affected so much by bad mastering. There's strange DC offsets in the waves, and dynamic range compression is excessive, too, even for speech!
The internet radio is fairly entertaining, so I've been on the border about buying the DJCD for a long time. I missed the pre-order chance, so I was going to forget about it. But I found a used copy while I was in Japan. Even then, I hesitated, but I ended up picking it up eventually. It wasn't even that cheap, at Y2,180, because it's a relatively recent release. Oh well. Maybe I'll bring it back and re-sell it the next time I visit Japan.
Oh, and on a somewhat unrelated note, I got to see an episode of ToLoveRu (word play on Trouble), real time on TV, while I was in Japan. My thought after watching it was, "people actually pay for this crap!?"
If you only saw the illustration on the net radio site, you wouldn't think the illustration is H, but it actually is. The actual illustration goes down even further when unfolded, and it's half way to tentacle theme, with cables.
