If I create a video & upload it onto my YouTube channel and there is music playing in the background, could this be something that could get my video removed by YouTube?
If the music is clearly incidental, you're within your legal rights... but it's a big grey area.
More thank likely, you won't get a strike and the video won't be removed, but it would be picked up by Content ID* (YouTube's 'Shazam' as mentioned by mitchell scott in an earlier post). Once video or audio are picked up by Content ID, the video typically gets a 3rd party copyright claim, the video will then be monetized and/ or tracked by the copyright holder, and, depending on licensing issues, may be turned off in certain parts of the world.
If you're lucky, you might get an option to remove the offending audio and YouTube will do it's best to silence it, but those results can be hit or miss or completely useless if you were talking over the music.
YouTube would also allow you to change the audio to a song in their library, but, again, that option is useless if there is talking or important audio in the video.
Lastly, you can always fight it, but that's close to impossible and rarely worth the headache it can cause.
