Looks like something I'd do. I find the graphs to be interesting visually.
Shouldn't the graph for 6DoIT have the last track as one song? Most of their albums have the epic at the end, which becomes clearing evident in the graphs. Probably common knowledge anyway, but still interesting to me.
They also make TA look like such an odd ball
One thing i might tweak is when the graphs are altogether - to much and it make it hard to read. Not sure how to fix that though.
Also on the separate graphs, if you made them all the same scale it makes it easier to see how they all compare.
I think I just let out my inner DT geek. That's ok because this is a "safe place" for that.
