The 2011 single. Dear Princess Twilight, Recently my friends and I were invited to handle an event commemorating the anniversary of your first visit to our world. I was a bit apprehensive, seeing as this person had little to nothing to do with you (aside from calling themself a "big fan"), but we ended up accepting anyway. I've decided to write to you, firstly to invite you this Friday, and to tell you about the strange form of music they choose. It's these things called "mashups", essentially you put two or more songs together to create a new one. While the Rainbooms may have plenty of musical experience this was sort of out of my field, but we decided to try it anyway and I think that we've all grown closer because of it. I hope to see you on Friday! Your friend, Sunset Shimmer  Please read the channel description for more information.
