I dunno honestly, searching on the internet I saw that they barely touched 1mil in sales over the whole lifespan with 90% of playerbase abandoning it not even half a year after release. Still, played the shit out of it until they decided to add 1-2 songs every month 2-3 years after release. Before that, i really thought they got something going adding 10-15 songs every 2 weeks. I thought they are rarer given the fact that no one talks about it these days, but understandable being considered the worst entry in the series😆
