^^ it's not Sony it's Apple. They code the file names to deter or prevent file sharing. The names only come up on Itunes once you dram them onto Itunes. There is a way around it since i had the same problem when i was trying to burn these songs with the actual names on a cd.
I had to drag the songs from iTunes to another Program and this was the only way it kept the names as they are.
1) If you have a laptop, connect the lappy to the ps3 with a cable and then drag the songs from ITunes onto the ps3.
2) Drag the songs from ITunes onto a USB memory stick and put the USB into the PS3.
3) Try load Itunes onto the PS3 .
