I used to use that site quite often. I think it's a great music discovery platform first and foremost, in fact, one of the best that I've ever used. I honestly listened to a much wider variety of music (and more music in general) much more frequently than I normally do, just because of how engaging the site itself was. I felt encouraged to post actively and it felt satisfying to increase the number of ratings and reviews. Plus, I made a very conscious effort to truly soak in every single detail of whatever I was listening to, even if I didn't like it on first listen.
I feel like there are some pretty major downsides, I quit using music cataloguing all together because of them. I eventually made listening to music habitual, rather than a form of entertainment. I was putting too much thought into whether or not I liked something. When you're constantly thinking in the back of your mind very specific reasons for why you enjoy or dislike something the first time you ever hear it, that completely destroys the pure emotion of the experience.
Its culture is pretty elitist, and it's easy to get sucked into it. I've gotten to the point where verbose and overly lettered "music reviews" make me sick to my stomach. You can't be in this mindset to truly enjoy music. At least from my perspective as a person who makes tracks, I can't relate to the perspective that critics or general over-analyzers have. Why are you describing this track like food?
I make what makes me feel good and immerses me in the creative process, where 5 hours can feel like 5 minutes. I can't even imagine having these incredibly complex novel-esque concepts that all of the "greatest albums of all time" apparently have and were envisioned by God your favorite 4chan approved artist to play out in the most perfectly sequential, divinely guided manner which can be perfectly expressed through flowery words and pretention.
The execution of a concept, for me anyway, is always just what truly engages you the most. Interweaving themes that link them together come about as almost unintentional and mostly subconscious. That's where the real beauty is, in my opinion.
