I mean .mp3 files only (not .mp3.exe , not an .exe renamed to .mp3 and smtg like that).

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

This has already been covered by a similar question: superuser.com/questions/445366/can-avi-files-contain-a-virus –  James Oct 2 '12 at 13:32
The principle behind multimedia containers is the same. AVI, MP3, doesn't matter here. I hope the great answer to the other question explains everything. –  slhck Oct 2 '12 at 13:36
Thanks everybody. You helped me quickly:) –  SEARAS Oct 2 '12 at 13:44

I suppose it's POSSIBLE to contain a virus, but it would have to be specifically engineered to exploit a flaw in a specific media player, or in the OS itself when it generates a preview (if it does). Since it usually just shoves the data through a player, I can't see this happening.

It wouldn't be because the file was executed, it would be because the file exploited a weakness in the software playing it. Buffer overruns, things like that. –  UtahJarhead Oct 2 '12 at 13:23
It means that music/video stream files can't contain a virus, which can execute himself (while running it). Isn't it? –  SEARAS Oct 2 '12 at 13:28
A virus is not always executable. –  UtahJarhead Oct 2 '12 at 13:40

The music player doesn't compile or run any type of executable commands on the OS. So even if a .mp3 had a virus, it can't be run/executed. So, the answer is no, it doesn't contain an executable virus (of course, if you wanted to write a music player which could also execute that would be a different matter :) but I don't think it would be popular ).
