iTunes is being a dick.
 

I was tinkering around with my iTunes purchased album from Entertainment System the other day and I converted the songs to MP3. Now they show up twice on a Smart Playlist. Oops. Went into the files and deleted them.

Well they're still showing up. Which instead of running the Smart playlist I have to compose my own by drag-n-drop. It isn't that bad, it's just annoying.

How do I get rid of these?

Attach a pair of high powered magnets to each side of your case, on either side of the hard drive.

Use library software that is not the bane of existance.

Unless I am missing something, this is easy.
 

iTunes is totally the devil because there's no Battlestar Galactica music on here.
Seriously if I don't find the full-length version of the Season One Opening Credits music I will shed enough tears to turn the United States of America into a swamp.

I wonder how long I'd keep a job at phone tech support if I did that to customers...
Oh I do use Winamp. But Nero for some reason hates burning CDs for my computer so I have to improvise.

Kick iTunes to the curb and buy a USB music player that has a drag-n-drop interface. Seriously they're cheaper as well as easier to use.

Or I could be reading too much into the "burning CDs" post above yours.
 

The Internet Giving Advice: A play in one act

"Hey guys my car's been having problems, based on the following description does anyone know what might be wrong?"

"Buy a bike!"

"HONDA SUX"

"Take the bus, snobbypants!"

"LEARN 2 WALK NUB"

Yeah, I have problems finding programs that'll burn CDs/DVDs properly. I find NTI works great for CDs, and Nero is needed for DVDs. I dunno why, it just works that way.

I did a quick search and found this script for removing dead tracks from your library. Why iTunes doesn't have like this automatically is stupidly baffling.
