So again, delete the AAC versions and use the Add To Library command to add your tracks from your external hard drive into iTunes. And set the iTunes Importing preference to MP3 so that nothing you import from a CD in the future comes in as any other format.
And just FYI, no one here works for Apple. Everyone is a volunteer, helping out as we have time and knowledge. So if you want help, try to be a bit more polite, since no one here owes you one minute of their time. I understand how you might be frustrated and how you might disagree with how iTunes does things, but if you just want to rant, then there are a lot of independent forums where you can do so to your heart's content, but it's not appropriate nor allowed (per the Terms of Use for the Discussions).
