I'm doing a texture pack for minecraft, and I want to use it later in my videos. Unfortunately there's a problem with this… I have a copyright song as bed-abound and can't use it. My question is now: Can I use the song if I turn up the bass so that it is only slightly overdriven? And if that does not work, are there any other methods I can use to use the song?
No, you must not. You may not use it without the permission of the copyright holder.
Can I use the song if I turn up the bass so that it is only slightly overdriven?
Then if it is not recognized by the automatic filter at all. A copyright infringement remains it anyway.
And if that does not work, are there any other methods I can use to use the song?
Yes: Obtain a license from the Copyright Holder (preferably in writing).
OK
OK
Whether YouTube recognizes the song through the modification, I do not know.
Actually you do not create a new, independent work by simply turning up the bass. Thus, the use is not allowed.
