I came across this (a fork of Clementine) in my ongoing quest to find something I enjoy using like I did iTunes when it first came out. This is close in a lot of ways! Maybe not quite as polished, but a huge improvement is that there's an sqlite db I can interact with directly if I want, so the data feels like it's really mine. (MacOS support is threatened, though, so if you use this on that platform, consider sponsoring).
