Concerning Clouds- Reminds me of what I might hear if I enter an exotic opium den from an old movie ^_^
Nous- Kinda like the background movie to an older spy/detective movie
Telephone- hehe, it's really fun to listen to! Zippy, upbeat
Turbine- more laid back. Science fiction like. Would go great with a space shooter game :]
Okay so.....the songs are too much like background music. There isn't much changing in each one, but they set up certain moods very well (like background music does). If that's what you are going for, then they were pretty effective. However, no crescendo's, no tempo changes, not much of a change in the thickness, or complexity, of the tunes within each song makes them not too good for active listening.
I'm guessing these were all made with a computer though. Makes it take a lot more effort to put musicality into the beat if you have to work to put phrasings in. What did you use to make these?
