Yeah kind of figured that. Even the annual best ofs aren't that well populated until a few years in. Wasn't psych that popular before '06 or something? I guess it was more underground?
I've been listening to it for 30 odd years so found other routes to it.
I do look at Rateyourmusic quite a bit. Can be good for tracklistings and catalogue order as well as releases but is variable. As is Discogs.
