I have a couple of thousand of them unsorted.
Made by Rolling Stone, he uses a weird numbering system
based on the date.
At least a quarter of them are vocals and many produced
older than a couple of years ago (when VirtualDJ introduced
stems) are RV - reduced vocal.
I have them scattered in a few folders and I'm sure that
there are a heap of dupes in there; they come to about
12~13GB
