Volumes 1&2 as well as the Monstercat Releases 1&2 have been pretty much engrained into my head, the songs they added the first couple years largely overlapped with my own taste and I've already been listening to a bunch of the artists prior. My favourites in terms of nostalgia are probably Hollywood Principle, Flying Forever and Skyforth. - Favourites in general are Zero Hero by Twilight and New Horizon by Protostar.
