As a rule of the thumb, if the song gets used for more then 2 or 3 vocals it becomes repetitive and boring.

Cover ong artists will cover the same song often anyway once its released. Plus, the song may not work for every vocaloid. As I said for Oliver and Kaito's cover, this was a poor choice and didn't do either a favour.

In contrast, Cendrillion (I think this was the song, I'm writing this blind) used for VY1 and VY2 is an example of a GOOD cover song used for demo purposes as it should off both vocals.

Ironically, "Fry me to the moon" was used twice for the Megpoid software, but was never actually used for the Megpoid English software. This is another example of poor choices because it was done with a Japanese vocal, the first time they got away with it but the second time... Was a little cringe worthy. And then there is Lily's V2 demos which everyone held as a example of taking demo songs with a pinch of salt prior to a vocaloids release.

Thus going back to Circus Monster... Well... With its track record of not sounding great in all 3 instances of its usage (the original is poorly mixed anyway), its proven its not a great demo song choice.
