Music Management Recommendation?

I hope this is the right place! I am a beginning music hoarder, and I was hoping for recommendations on what software you use to manage and listen to your music. I started with iTunes, and moved on to Media Monkey; I have decided I hate MM. The syncing to my device is a pain, and the album art is not correct.

With the caveat of I am not super tech savvy, do you have a management app or software that you love and can recommend? Or, any that are terrible and I should steer clear?
