Due to the fact that the canon list is extremely long and I assume that some people are lazy, if you're interested in involving yourself in one of the following canon stories, look over at the canon list for more details.
If you want the song lyrics and/or music video of the song, click on the name. For some songs I put the lyrics solely because I hated the videos up on Youtube but feel free to Youtube them. Some music videos are relevant to the plot so... If they're there and you're intrigued, watch them!
