“The group responsible for these “Happy Birthday, [Your Name Here]” songs, Birthday Song Crew, apparently didn’t want to shell out licensing fees for the familiar “Happy Birthday” song, nor risk legal action for using it without permission. Instead they simply wrote some new tunes with deceptive titles “Happy Birthday (Reggae)”, “Happy Birthday (Jazzy),” and “Happy Birthday (Hillbilly),” each of which is a depressingly bad genre pastiche. They are not the “Happy Birthday” you’re looking for, and on top of that, they’re musically awful. You may also notice in the screenshot above that some names appear twice. That, as far as I can tell, is because the “Happy Birthday, Jerome!” at the very beginning of the song has a slightly different intonation on some tracks, and the duplicated names are the ones where both intonations are available.”
Totally fascinating post about music spammers & the detection thereof.
