Weird playback bug - switching songs

[B-MoN]

Hey guys,
I've recently noticed a bug regarding only a few songs, but it occurs every time I try to play such a file which is quite annoying though because I can't possibly listen to them.
I'm using a SanDisk Sansa Clip+ and the latest rockbox version.

The issue is that while playing a particular song, the song suddenly switches to a part of a different song without me doing anything that could make a song change happen. However, the song doesn't really switch, the ID3-tags of the old one still remain on the display and even the progress bar keeps running, just the audio is messed up. I can easily reproduce this bug because it always occurs when playing some particular songs. I can search in the song using the fast forward and rewind option, this does not change the played audio back to normal. Sometimes  there are more than just one audio-swap.
The files are stored on a 32gb microSD card.
I have no problem with the files on my PC, I can easily listen to them there without any kind of weird audio swapping.

I already searched for this kind of bug, but I didn't even really know what I should call the problem like, so here is my post... If there is already a thread existing dealing with this problem, I feel sorry for wasting your time.
I really appreciate using rockbox, thanksalot and keep up the good work!

Best regards,
Simon

you'll need to upload the file somewhere, this sounds very much like filesysstem corruption or a broken file.

The really weird thing is that this problem only occurs when I try to play the file on my Sansa with Rockbox, my PC plays it just as usual without any bugs...

Okey, I'm gonna upload it somewhere tomorrow, quite busy at the moment.
Thanks for your answer so far!
