How to get your music thick yet tight?

How to make your end results sound thick, full, present, tight and CLEAR? I wrote a long post but reddit erased it for FFS. The question stands: How do I achieve high quality sound that has meat in it, ya kno? That feels present yet filling. I got fire production and songwriting IMO, but the end results doesn't sound like the music out there. WHAT am I doing differently? I tried everything. What is the secret?
