Playlisting is a great tool - a handy way for you to remember (and evidence, through screenshotting) which videos you've viewed for your research. You could (as I do) split this up into multiple themed playlists.
I'll gather your samples, rough cuts and eventually final cuts in the playlist below. It would be useful if you comment on each others. You can also view many past A2 music videos through my channel, and look at current A2 blogs to see more as they progress.
I'm happy to comment on a blog post if you prefer - just email me a link to the post where you've embedded your latest cut.
