Samsung E570 problem playing certain mp3 and jpg

Hi,

Since today my daughter uses this ladyphone together with an microSD card.
She just copied some mp3 and jpg files from here computer to the card and
did put the card in her phone. The problem is that many mp3 don't play and
some jpg won't show. I suspect that the phone has requirements the files
have to fullfil???

Also many mp3 show up as unknown. Does it mean that mp3 tags are missing?

thx

nobody? please!
