If you suck at music making you can try out this algorithmic music generator(It’s free) CGMusic.  This generates midi files, which you can then turn into mp3 with some random software around the internet, a good one for chiptuning ^^ is this one: Gashisoft GXSCC. Everything mentioned here is 100% free, all the composed pieces grants you the right to use them commercially if you wish to. I hope this helps someone 😉
