Thank you for asking
Current collection, regularly expanded and occasionally culled:
802 albums, including 27 by Various Artists
690 artists + the "various artists"
110 GBs (118,565,819,398 bytes) -both counts per Windows Explorer
Stored on the 2TB hard disk in my NUC, rather than its 256 SSD. It runs very satisfactorily and reliably, under Windows 7, using MusicBee 95% of the time. About 95% consists of ripped CDs, with 95% in WMA lossless, FLAC, or 320 MP3. I also use MB on a Win 10-updated Surface Pro 2 that has all the same music, frequently-updated, stored on an SD card. The SP2 music is played 95% through Bluetooth to my 2-channel stereo, also very satisfactorily and reliably. Spend many pleasant, relaxing hours listening to great artistry, enhanced maybe 50% of the time by the visuals and bios on MusicBee's Now Playing screen. Thank you MB developers. Enjoy the music!
NB: I also regularly BACK UP my NUC-stored music on an external 5TB drive, and redundantly on a 2TB one.
