So, after ripping approximately 300 CDs, I realized I didn't have Normalization enabled. I was wondering what everybodys' opinion was on it. Should I go back and re-rip the CDs? I've noticed on quite a few CDs I've been ripping lately, I've been getting peaks of 50%.

Is there any (quick) way to check to see if a file is normalized? I know I could open a particular MP3 in a WAV editor and find out, but that would be too time consuming.
