1 - As for the state of the music, there are plenty of opinions on things like music! Actually, there seems to be an entire industry based on that here in Struxta! Talking to the right people, he may even start to hear rumors about an underground singing competition. All of the best musicians will show off their chops down there! If he likes music, he should go check it out! With regards to the type of music tastes they have and performances they enjoy, it ranges wildly - just like in any major city! Some prefer classical, some enjoy more techno pop, others have a soft spot for jazz...it all depends on what he's looking for. As for jobs, there are many different types of stores - mostly in-person spotify stands, where natives can come and download music directly into their own personal server! He would be welcome to be a greeter there!

2 - He can make as many friends as he has the time and energy to make! But with regards to the creative process specifically, he would actually find that 'creativity' leans heavily on the lines of mathematics. In the same way music can be mathematically defined, much of the art and music here runs along those lines.

3 + 4 - so there is actually an entire industry based around The Races, which means that Leo would be able to find places to sit and chat with other viewers, themed parlors, designed specifically around the experience of watching the Races! However, there are also more off-limits areas where the vehicles are designed and created. It would depend on where he would be looking for inspiration!
