Love this site and just stumbled on it. I don't know my way around yet but is there a category to share things like Greatest Hits compilations where multiple artists are doing a genre/era or where multiple artists are tributing songs of an icon (like the Todd Rundgren or Tom Waits tributes) or an icon sings other artists' hits (like the Frankie Valli "Romancing the 60s" where he's singing other artist's hits from an era)?
