You know what sounded like fun to me? If you guys suggested topics to write about - like little assignments - and I'll try writing one with that suggested topic. It can range from something like "write a song about your trip to the US" to "write a song about a floating piece of paper that floats around the Arctic circle". Whatever you like to hear a song about!
I cannot promise it will be a good song, but you might be able to get a good laugh (or cry?) out of it!
