2g Ipod nano 4gb playback help

Hey, i have a 2nd generation ipod nano 4gb.
During some songs on my ipod, it doesnt seem to want to play the song.
If i however fastforward it it may play a few seconds or if im really luck it will play it whole.
I fanyone can shed some light on this i will thank you.

are the files damaged?

nope the files al play perfectly on windows media player and itunes player

are the ID3 tags intact and do they contain any special characters?

well ill check the tags with mp3tag in a minute but the only special characters are maybe a comma and some brackets

those shouldnt screw it up.

how can i tell if the tags have errors.

Reset/restart your Ipod. If you need instructions visit the apple website.http://www.apple.com/support/Hope that works

im not going to reset it cos of a few songs.

Well,get rid of the problem songs,or get the songs again from a different source.

It's definitely the songs, one of my RATM songs use to just skips a minute in the middle, so I got a new one.
