One of my friends use Pocket (https://getpocket.com/) for this purpose. Firefox actually has Pocket built into the browser, which actually makes it rather convenient. I'm not sure if they have a note-taking/summary feature, though.
I've never really used it because by the time I had found out about it, I had already built something similar in the form of a webapp using Parse.
At the end of each piece there was this "Applause!" at the end - it would be cool if it were to be converted into a button which actually plays an applause when clicked (I thought it was a button when I first saw it).
