Have you considered making more discussion tabs/areas so comments can be grouped with their subject matter? EXAMPLE: A variety to appear next to "All" & "General Discussion" such as... "Practica" (for posting videos of songs you are working on), "Start Here!" (for fielding orientation questions and posting intros, if not a separate one for intros too), "Medicine Music 101" (for postings relevant to materials in its 5 'modules'), "Suggested Playlists" (for discussion and suggestions of such sort), and one discussion area for each or all songs called "Songs", or labeled as each song's title), etc? :)
