This depends entirely on whether or not you are serious about music production. For example, if you are a music production hobbyist and like doing it for fun, 8GB RAM will suit you just fine. However, suppose you are a professional music producer or are looking to get more into it. In that case, I recommend having at least 16GB of RAM.  This is undoubtedly a pretty solid amount, but remember that 32GB RAM or more would be even better.
