I’m guessing their using some sort of effect on the music like putting it in 4x speed and slowing it down in studio, or uploading the vocals, instrumental, etc, separately then adding them all in studio.
Yeah, but how is their game still up if they are using album covers (which cant really be distorted beyond seperating them into multiple peices), along with blatantly using the artists name?
This could be it, although I haven’t done too much research on this but this partnered with Universal Music Group (UMG), Republic Records and Styngr, which people like Billie Eilish, and SZA, are not affiliated with.
Karaoke doesn’t have any licensing rights or partnerships at all. They’re using some method that only works in their game which bypasses the copyright filter.
