I'm not positive the embedding is going to work here; the first couple times I tried it, the video didn't show up in preview. (Here is the link to YouTube, if it doesn't work.)
This one is unusual because 1) A lot of people have heard it already (the video has 280,000 views), and 2) It's pretty. "Pretty" isn't a quality one normally finds in mashups (I can think of a few others; "Building an Enigma" comes to mind [UPDATE: Sorry, the link to "Building an Enigma" was broken shortly after I posted this. It's Sarah McLachlan / Enigma, if you want to try to search for it.], as does DJ Earworm's 2008 United State of Pop, at least in places), and I'm not sure why. Maybe it's harder to do?
Anyway. I got very excited about Norwegian Recycling when I heard this, hunted all over the internet for more of his stuff,1 downloaded a shit-ton of it, and then was quietly disappointed. It's not that the other stuff is bad -- it may yet grow on me, actually, and I like "Miracles" (which also probably counts as "pretty") well enough2 -- but it all sounds very much the same, somehow. Maybe I just haven't listened to them enough yet. I don't know. In any case, this is easily my favorite of the songs he's done.
1 Why is it always "his?" Where are the female mashup artists? I know there have to be some out there somewhere. 1000 PATSP points to anybody who can point me to one. (PATSP points are not redeemable for cash, goods or services.)
2 Actually, more people seem to like "Miracles" than "Singularity;" "Miracles" has over a million hits. I think "Singularity" is the better composition, though. Some of that is because I get all itchy whenever I hear the word "miracle" that many times in a non-mayonnaise context.
