Not loud enough.

I've never heard, ever in the history of music I've listened to, one album that was as seriously distorted transitioning from flac to mp3 as this one apparently is. It could also be V0, as I never get music rips in it or other variable/<320 CBR formats and don't know about the technical aspects of it at all.
Is this:

Mp3 and other lossy compression algorithms rely on filtering out certain frequency bands. This alters the shape of the waveform, but it doesn't always result in smaller amplitude as one would expect.
Here's an example of 440hz square wave with 90% amplitude, and below the same waveform with a steep low-pass filter at 2khz applied to it. The RMS level if the signal drops, but the resulting signals peaks are higher and go over the -0db limit resulting in clipping. The same effect can be observed in mp3 file compression where the peaks of the source file are close to the maximum.
In The Aeroplane Over The Sea doesn't clip. It is heavily compressed though and close to the -0db, but I like the sound. It makes it sound big and meaty, I don't think all music should sound as natural as possible, but of course simply brickwalling everything isn't always good and doesn't fit for all types of music.

Really? That's odd, it's my friend's uploading service. I had no idea of such behaviour.
Here's the file.
