Looking thru the available software, the few I have tried (not naming just yet) have being rather lacking.
Some wouldnt read tags from the files, most seem to only support a few formats and all of them seem to want to scan thru all the audio files on the mame machine.
I have all my MP3s stored on a central server with many many HDDs in it. This is plugged into the lan and I access the files via the UNC name (*NOT* a mapped drive letter) - relocating files to be \genre\artist\album\xx.title or similar is not an option because of the amount of playlists I have built with them just where I want them.
As the lan is somewhat slow, I want to use something where I run a server on the PC with the songs, and the client on the mame machine queries that rather then opening up every audio file to pull tags out.
I saw one of the programs used mysql, I am hoping for something that uses either an access database or mssql as my last attempt at using mysql on a windows platform was an exercise in futility.
