consistency of terminology - type
 

Both the Search and Library tabs display a table which has a column heading "Type". This is good, it shows you the file type. In the case of audio files it shows you the type of codec used to encode the sound, OGG, MP3 or whatever.

The audio search selection panel (More Search Options) has a select box headed "Type". This is great, well it would be if it enabled you to select an encoding type. Instead the select box pertains to a mysterious property relating to audio content type, possible values are Song, Speech, Audiobook. I am sure this is of use to someone but perhaps it would be better if it did not mislead users into thinking it is a means of selecting a preference for one encoding over another. e.g. OGG in preference to MP3.
