Organiser for playing uncompressed music from NAS to Kef LS50 wireless 2

[Enquiries]

I have transferred 900 CD to my computer hard drive in FLAC format UNCOMPRESSED. I plan to transfer this to a NAS drive from which I can access the music to play on my wireless spearker system driven by a pair of KEF LS50 Wireless speakers which have buily in sssssssss. Also to my study on smaller speakers.
I have used the Sonos interface where can I find a music organiser which shows all my music and form which I can select and play albums or tracks. Ideally also create playlists.

Here is a video on how to link a NAS to SONOS https://www.youtube.com/watch?v=bppg9K28sPg
You can go as simple as DS218play or something more future proof like ds220+.
Or Qnap 51D/ 53b/ 64 series
Here is how to enable SMB https://nascompares.com/answer/smb-v1-co...for-sonos/

Enabling DLNA will broadcast available media libraries to local network devices including TVs.

I hope this helps.
