For me it is more important to be able to recognize why you like certain songs
Thanks for the Ronald Jenkees links. Reminds me of music you'd here watching demos back in the days of the 486. I certainly found it enjoyable but I can't really imagine keeping it on a playlist of mine because, in my mind, it's attached to that one general experience which doesn't occur for me anymore. It doesn't work for me as something to listen to in the car, while walking, to have in the background, or while trying to code. That's not to say that I won't ever find something else to connect the music to, it's just that I only have the one way to relate to it right now.
It may very well be that you have enough in common with that 70 year old guy that you are able to relate to music that he does as well. Kind of a broad sweeping statement though that might not really hold water. But I absolutly agree that it is important to recognize why you like certain songs. It's like I told my niece, "Though it's not music I care for, it's ok to like music like Justin Beiber. But I want you to ask yourself whether you like it because of something that the music is to you or if it is just because it's what all your friends like."
Though you didn't ask me and my musical talents and ability to provide informed input are limited, I generally liked "The Cat". The instruments and general melody seem to be appropriate for a cat and the chords in the background convey a sense of walking. Overall it sounds like it's something that you'd find as part of a game and I know the tune going to be stuck in my head for the next few hours. The main criticism I have is that I think you need a bridge of some kind. It's kinda like the cat never stops walking, never stops to look around, never stops to check its direction. You break up the primary melody into a couple variations that keeps things fairly fresh yet I keep expecting a moment or two where the constant progression of the main chords switches to something else. That being said, I'm not sure what sort of bridge would be appropriate or where exactly it should go.
