Alternatives to iTunes (Mac)

[Mohmm]

Apple's iTunes is getting more and more obtrusive such that I urgently need to find a replacement. I used iTunes only for keeping order on my collection of 3k+ albums. Recently however, iTunes permanently checks with the iTunes account and server and when you prevent it from connecting you get lots of warnings interrupting the flow of music. They want to loose customers? So be it.

Please, can you suggest alternatives for taking over the system of iTunes library, files and folders and being as versatile in ordering and labelling files as is iTunes? I play music by Roon, but don't trust its capacity of keeping the library in order after reading reports on disasters.

Thanks.
