You should not post unless sober,, or in a better mood. , The Op is a regular member here and has a legit concern.
I assumed that a soundcloud free account always compressed your file. So I always post at MP3 160kbps and they have all sound fine. I like Soundclouds clean interface. I find sounclick cluttered and clunky to navigate. I find Reverbination slow to play on my funky internet.
Soundcloud songs always play without hick ups here in the bush.
