WAV sounds fine @16/96k then i upload to SoundCloud...bass is garbage?

My demo sounded fine before I uploaded to it SoundCloud, even @
16/44.1K WAV. The problem is the annoying saturated sound which only
affects low frequencies. So it doesn't seem like a sample rate issue.
Due to the rarity of this I am left thinking it is the material
itself.

Listen for yourself! Thanks in advance
