For me, I think the interest would be in listening to the mixed parts.
Was definitely impressed at how many individual tracks are listed that I wasn’t aware of but I made the decision years ago not to just collect stuff for the sake of it, if it isn’t in the last month or two just simply because of the high likelihood that it will just get stored on my HDD and never get played. When that happens, it just adds to the sense that there is too much disposable music. That said, if any real gems come up, I will make the effort to grab them as a potential future classic but the bar is set quite high for that.
