lol, so you're still stickin to CD and not mp3 ?

I stick with records and tube amps as they give the best and warmest sounds that CDs pale in comparison too. MP3 is crappy digitized sound that bit rates can improve dramatacilly on but they still sound flat.
However to answer the question about compression yes it lowers the processor usage in terms of decoding but it also eats up a significant portion of bandwidth to the CPU. There are plenty of lossless compression techniques that sound or look just as good.
When you start talking about video, textures, models, sound etc you can easily surpass the emory bandwidth of your system however many compression techniques can be handled with predetermined instruction sets that zip right through the CPU.
Not all compression is lossless which gives it a bad name. MPEG for instance uses what is called a predictive(P frames) and Bi-directional(B frames) frames which makes predictive(or predictive and draws macros from the next frame in blocks of nXn pixels) changes to the original I frame(Like a JPEG[already lossy Discrete Cosine Transformation blocks]). However we use it all the time for broadcast transmissions, movies, games web browsing and such because the compression is still good(you just don't want to edit with it like you would HuffYUV and wavelet compressions) because it woudl really screw it up.
However 30 MBps vs 1.18 GBps(720P uncompressed BW without any sound) is a significant difference in bandwidth that would allow for other things for the CPU to access instead of just video
