this is literally driving me insane..and this is crazy..

there's so justification of this thing...every1 ..i mean every other person did a video on compilation of rock/punk/etc etc songs and posted it on yt without any hassels...
well inspired by those ppl,i did one too but everytime i upload it the audio is removed cuz it contains bla bla copyright shits...
so my question is how come they did it while i aint able to???..even the other videos dont have a so called DISCLAIMER or Copyright notice..
i want a fr***ing answer....

thanx for reading btw
