^ They're weird. But entertaining.
As for the topic, it's weird because I listened to this particular U2 Popmart Live in Mexico CD on Spotify a few weeks back (except it was in my local library and NOT on Spotify--I just used Spotify to listen to it). I'm wondering if perhaps Spotify somehow took it and uploaded for others to stream? Not sure if that's how they do things, though I assume not.
Anyway, it's a great show from what I've heard. Great sound quality.
