ID3 v1 and v1.1 (hardly worthy of it's own version number) is typically the
last 128 bytes of a file. ID3 v2 is typically at the start of the file and
uses a method they call "synchsafe" to keep it from being interpreted as a
valid mp3 frame.

8192 in shoutcast I believe.

I'm sending from winamp with the FHG codec.

impressed me. ;)
