Would this violate music copyrights?

Even if a random song is playing on the radio, barely audible in the background, you still need licensing to use that song in your film. Otherwise, yes, it would be infringement.

specific, you may want a license to create, reproduce, post or distribute this style of "spinoff artwork" of music created by capacity of others that's still below copyright. 17 USC § one hundred fifteen. each music is nicely worth as much as $a hundred and fifty,000 for copyright infringement of a registered copyright, whether you do no longer sell any of them. Copyright infringement would not require evidence which you're "making a living". criminal violation, with federal reformatory time, additionally would not require evidence which you made any own earnings out of your copyright infringement; purely which you allotted a minimum of $a million,000 nicely worth of stuff (a misdemeanor). in case you made ANY funds out of your intentional copyright infringement, this is a federal criminal. 18 USC § 2319 US criminal Code.

Music copyright is not worth the paper it is printed on. As with any copyright.

This charade will go on for a few more years, and if the world does not end, greed will crumble into the abyss it belongs and people, society and community will be better for it.

No that's a complete textbook example of fair use.
