I'm working on a new Songwriting Assignment Generator. If you ever feel at a loss for what to write a song about, just visit the generator, and it will always have a new randomly-generated idea for you.
I don't expect people to take this tool very seriously. Life is full of interesting things that could be turned into songs, and I hope you're already keeping an ever-expanding idea list in your lyrics journal. But if you feel stuck or feel like you need to try something completely different, give the Songwriting Assignment Generator a visit. It might spark some ideas and help get you started on something new.
If you have any comments or suggestions for the generator, please leave a comment on this blog post.
