In 5 days from now I think, is the 4th of July. ( americas independence ) can you write a song about it? If so, that would be good for the event. In case your struggling, try listening to schoolhouse rock or watch the history channel about it.
i think the main struggle would be completing a recording on time. i'd have to start now and rush it. that also leaves no time for a video, and i would also have to put everything else i'm doing on pause. also i don't particularly like focusing on holidays because it seems like everyone else is already focusing on them. what about all the other days?
