Currently only the most basic tags can be used to format file names or can be picked up from file names. There are other tags that I would like to have used such as the grouping. TIT1,2,3.
There is also a problem with the comment field. When the MP3 was generated by iTunes the comment field is often nonsense. Winamp agrees with iTunes, but both Jaikoz and Windows XP show nonsense in the comment field. So it is 2 for 2 as to whether it is correct.
