It sounds a bit off-pitch to me... Otherwise good job!
I don't suppose you were inspired at all by Blocky Gulch Mine?
You can't judge a song upon it's simplicity, that's just ignorant. Simple or not, in the end it's the message. Have you noticed some of the most popular songs have a 4 chord structure?
not listening to songs due to simplicity is fine. wouldnt judging it on simplicity also include the message? for example, lullabies are very boring because the message and actual music itself is very simple.
Haha yeah I thought at first that you just couldn't get the pitch right because.. blockland, but noticed that you actually mismatched the chords and melody. Well, I guess it is a way to do it tho. Makes it sound sort of goofy n dumb. :)
