It's Ubisoft… of COURSE they were selling it in the worst possible state. XD
The community content makes it absolutely worth it, and I highly recommend it. Fair warning, it IS community created content. I've had to re-chart and submit updates to some of the song charts on there, but I also feel like that's helped me become a better musician as well. Knowing the song well enough that I can tell when it's wrong and then I get to use (ToneLib-Jam, for me personally) another piece of the toolkit to fix it and resubmit.
Dealing with this shit.
