track plays longer than track length

[punkjoy]

I've noticed that my MP3 tracks do not play gapless in GMMP. On investigating further I've noticed that the tracks play for 11s longer than the displayed track length. I play the same files in Windows Media Player and they play for exactly the stated track length and the track lengths are identical.
I have gapless play enabled on my Samsung Galaxy Ace 2 phone. In show compatibility it lists Yes for gapless playback.
I have 1.4.0 installed.
I just tried the phones Music Player and it also plays to the correct track length. It therefore seems to be something that GMMP is doing.
Music can still be heard when the track length has been exceeded so its not filling it with silence.
The MP3 files were converted from FLAC.
Thoughts?

if you want to send me a file to look at.. email it to [e-mail]

that being said the timing on now playing is not %100 accurate but that should not effect gapless playback.. are you saying you are getting gaps between songs? GMMP shouldnt fill anything with silence if its not on the original version of the song
