Art, jazz, classical music... All very noble and fun pursuits. Ever see yourself owning a famous violin made by Strad in Cremona? Ever see yourself collecting concert pianos? Collecting original scores of music hand-written by a famous artist over a century ago? Maybe the Hi-Fi route where you get techy with speakers, amplifiers, gold plated cables, etc.
A lot of fun to have there. I got myself a super complex music box in Singapore last year. These are truly beautiful creations that are underappreciated.
