There is a channel here for recommending music to one another. I posted a request and got a bunch of replies, each song as a post, child to the original request. I listened to each song and commented whether I liked it or not and why beneath each post. After a while I had a bunch of comments written but when I went to submit the first one, the page re loaded and all the other comments were lost. For tipping, I wanted to be able to give each song reply a small tip, and then manually add bigger tips to better songs. Hope that makes sense!
