Ya, music is different from movies. Just a different beast really. They connect on different levels. Many people will watch a movie once and never want to watch it again even if they really liked it. With music people can listen to something they like on repeat. Which is also why I never listen to the radio, they tend to do that with the songs I hate the most.
Quite often the original artist will provide many takes on the same song. Sarah McLachlan provided two excellent versions of Possession on Fumbling Towards Ecstasy:
First track on CD:
Last track on CD:
Not sure which one I love more, but I appreciate them both as separate works and would have no problems listening to one immediately after the other.
Then there are the remix CDs. Sarah has released several 0f those, and of course U2 is famous for their long list of remixes. Paul Oakenfold (Perfecto) did a good job of remixing many of the Achtung Baby era songs, but the one that really stands out for me is Brian Eno's remix (more of a remake actually) of Zoo Station called Bottoms (released only to the official fan club):
The funny thing about Zoo Station is that the original sounds like something NIN would do. But when NIN covered the song, it sounds like something U2 would do:
Where as the U2's original sounds like a bunch of broken studio equipment mushed together in the most angry kind of way possible you'd expect from NIN and definitely not from the guys who recorded I Still Haven't Found What I'm Looking For.
I think U2 out Nine Inch Nailed NIN on this one.
And since we're talking about Zoo Station, one interesting tid bit about that song is that their live version on the ZooTV tour started off with a very loud 50Hz hum (you can also hear it
here). I didn't realize the significance of that until I actually went to Zoo Station in Berlin. The trains there are electric and you hear this very loud 50Hz hum where ever you go in the station. It was the first thing I noticed when I arrived in Berlin by train next to the Zoo.
