Today one my CDs was found on the alternate server. In this case the file name scheme worked. So you only got to fix the problem that the scheme does not work for titles not found.
For your information, I like to explain why I need this. I am often copying audio books from CDs. They come on multiple CDs. I like to copy them into one folder with alphabetical names, like 01-01, 01-02, ..., 02-01 etc., so the MP3 player plays them in the right order. So I need a file naming scheme, involving the CD number 01, which I enter, and the track number.
By the way, I have to copy the file name to the title with another software. This is annoying, but I need to do this with all grabbers I know of. Many MP3 players sort the files by title.
Maybe you could fix the problem with the file names, and also make an option to use the file name for the title tag as well?!
Otherwise, your software is good. The encoder results are a lot better than the results of the free LAME encoder, given the same file size. It is also faster.
