Yes. Sorry, but as a music geek, this is actually pretty terrible - not even close to bad first year composition student pastiche, and a long way short of David Cope's EMI, which is probably the current state of the art.

I wish coders who are trying to do something in a creative domain would learn the basics and not just assume they can throw some simple algorithms at an artform and get anything close to an acceptable result.

No one is going to take a coder seriously if they can't code fizzbuzz.

Here's a thing to know: all the arts have their own equivalents. If you don't know what they are, learn them. Then maybe you can start thinking about non-toy algorithms and data structures that are going to impress an audience that cares more about quality of output than implementation details.

Most people who start working with domain-specific knowledge find it's much harder than they think.
