TOPR, VSZD why are my songs named like this?

Question

And how do i change them?

Answer 1

There are utilities available from third-parties that allow taking songs of the iPod and converting their names back into a more human-readable format. Unfortunately I don't know the names of them (never actully used any, I use my Nano mostly for podcasts.) A quick search on google should return some results.
I'm guessing you want to play the songs in something other than iTunes or wish to move songs between computers. I too found it kind of annoying as my old mp3 player cataloged without renaming or relocating files. Though normal behavior for iTunes, it is annoying if you wish to use the iPod without iTunes when plugged into a computer, or wish to transfer songs between systems.
Some media players, such as winamp, will read the ID3 tags, but having to import all songs to generate a complete list then remove unwanted songs seems a bit much to play a select few, though is possible if the songs are all unprotected AAC or mp3 files.
If your music lacks the needed tags, you can use MusicBrainz [musicbrainz.org] for free to attempt to add proper tagging. I've had mixed success with this, normally it works well, but sometimes server load is high and you need to resubmit a few times before everything detects.
