Those blips and spaces on MP3 files, seem to just be bad Quality recordings. For Example, if I try and rip MP3 files from CD while the PC is running something else intense at the same time (like limewire) I will get blips, pops, and spaces on the file. I have to rip on a clean, quite PC (no other applications running) yo ensure perfect Q. There seems to be no way to fix them, just download a different version, and better luck with it!!
