First of all let me tell you that Subsonic is amazing. I love music and this tool is the definitive response for all I need. Thanks.
My suggestion is to put more options for search. For example search on the comments. When I organized my collection I had put all the soundtracks in a directory. Usually when you look for a soundtrack you know the film title but not the artist. Indeed I have erase the name of the artist from the directory tag of the album to make easier the search for the film (I know...perhaps a little stupid). I'm writing comments on the album level, I have put in the artist, so I can see who's the guilty one, hehehe, but if only I could find this info in the search....
Thanks for the time and sorry about my english.
