As I noted in that thread, the mp3 compressed at 320 was originally at 128. I had to edit some things out so I uncompressed it to wav, edited it and then re-compressed at 320.(would love similar quality versions of the B sides of "Last night", I downloaded the BBC compilation, but the files sound sourced from a lower bitrate, maybe from the 128k poster previously, the EQ sounds different on the 3 of them and there is one which sounds abnormally compressed...)
The other two mp3s from the CD single were exactly as I found them.
The EQ does not sound different at all, to my ears. They all come from the same source.
