so i have the samsung a950.
and i got the transflash memory card in 1 gig.
i syncronized the songs to the phone trough a cable cord,
using the windows media player 10.
the process was fine.

but when i try to play the music with my phone,
some will not work,
some will play for a few mintues then it will keep pausing and then skips to the next song.

sometimes it will either say "player error" or "unable to play ... "

could the problem be the memory card?
or what i can i do to fix this problem?
it's making me frustrated.
