over the past 5 years I've had this weird YouTube ad come to mind every so often. it's an ad for some Floam-like kids toy, but that's not what's weird, for some reason the background to this ad uses a bizarre, like, bootleg version of Unreeeal Superhero 3.

I initially thought that it was a case of someone on the ad team getting SiIvaGunnered and putting some HQR of the song in instead of the original. the thing is, I cannot source the version of this song, so it can't be that. so, the only answer is that, during production of this ad, the real song was used, thinking that it was Public Domain or something, until someone thought to check, at which point, for whatever reason, rather than using a different song that they did have the licence to, they had someone create a definitely-not-legally-distinct remix of the song to use instead.
