I've been hanging out on Tapas too, and I've been really enjoying their Soundcloud feature. I also got really excited when I found out my friend "André" posted his songs on Soundcloud too, so I want to feature those with Chapters 54 and 57. Those songs are going to be difficult for people to locate without a direct Soundcloud link.
Anyway, the point is that the Tapas system is great, and I'm not posting a song with every single chapter, but I love it! The default is for the song not to play, but with one click, you can turn the music on.

However, I can't seem to get my full illustrations up on Tapas, just thumbnails, so Scribble Hub is ahead of the curve there.
