Firstly, I'm not here to talk about the scammy aspects. Just features.

I'm thinking of getting a Pro/Pro+ plan for one year so that I can mass download every non-official song I might want. I do like the side benefit of being able to view official scores and screenshot them for reference, but my main desire here is pieces that can be transposed/edited in the software.

I'm learning piano and planning to sing while I play, which is why I want them to be transposed to my vocal range, and edited to be a bit simpler. Is it pretty standard that the downloadable pieces can be transposed and edited? Or is it more uncommon?
