The problem with the mp3 to midi converter is that you can't really make a good conversion. A mp3 is compressed audio to a medium or lower quality while a midi is a more a detailed and exact map of all notes, instruments and note lengths. It's just not the same thing. Those converters will work for simple piano mp3 but other than that it's a failure or a very approximate result you'll get.

For VG music this is a good midi source: http://www.vgmusic.com/

Otherwise you can find a lot of midi online in different places. Some are specialized in movies midi or pop music. Finally if you don't find I got two ~50 000 midi archives on my disc. You can always send me a pm for something you can't find online. One is basically all the GeoCities existing midis before its closing and the second one a more structured collection of various midis.
