This is part of the limited edition Madoka Magica Blu-ray (and probably DVD, too) volume 1.
Speech portion of the track 1 has flawless audio quality. Music part is not so good, even when the music is used as part of the drama. It's not that bad, though.
Track 2 and 3 are obviously compressed, but it's better than I've seen elsewhere. Since I no longer buy Japanese vocal CDs due to their terrible sound quality, the only way I can end up with such is if a music CD is included as a bonus of some other product. And for that, I'm happy with this one.
It is HIGHLY recommended that you watch the first 10 episodes of the anime before listening to this drama CD. Otherwise, you'll either get confused, or get spoiled. That is all I will say about the drama.
I think this is the first time I've heard Yuuki Aoi sing. Her speaking voice has a bit of peculiarity, and I see (or rather hear) that she does that when she sings, too. I don't think I can explain what that is, so I won't try. For the record, I'm not saying anything bad about her voice. I'm just saying that she has it. If anything, I actually appreciate it because it helps me recognize her voice ;)
As for the song, it's a simple little piece. I like it.
