Folder browsing can sometimes be useful and MinimServer does offer this option at the bottom of its initial selection menu, but the primary purpose of MinimServer is to allow browsing according to the metadata values stored in each music file, just as Glider does. However, MinimServer handles the metadata in a far more sophisticated manner.
When you select almost any genre of popular music, the focus is on the Artist and Album. You might then cherry pick a specific Track. The selection process for classical music is totally different. Here you would usually start by picking a Composer, such as Vivaldi. The next step is normally to choose a Work by that composer, e.g. The Four Seasons. If you have multiple recordings of The Four Seasons you might then select by Artist, e.g. The Academy of St Martin in the Fields, conducted by Sir Neville Marriner. MinimServer goes far beyond this basic selection process, but I won’t expand on that here.
At present, Glider calls every track a ‘Song’, which is simply ludicrous for classical music. Verdi’s Requiem is a vocal work, but it is not a song. Beethoven’s symphonies and sonatas are not songs. Only a very small proportion of my classical CD collection is made up of songs, i.e. a solo singer with or without accompaniment.
Glider lets me choose by composer, but it doesn’t let me choose only composers of classical music. I can choose by genre (in my case, that means Classical or Non-classical), but then I can’t select by composer. Unlike MinimServer, Glider fails to offer me any choice by Sub-Genre, a tag I use to subdivide both classical and non-classical recordings and which greatly speeds up the selection process. Glider also suppresses the presentation of my Work tag. Selecting classical music via the Glider interface is thus much more laborious than when using MinimServer.
However, it would be totally pointless for Glider to try and recreate the excellent work already done by MinimServer. You simply need to offer the option of accepting the original browsing tree offered by any available music server.
