Where did you get that document?

The first 4 (8) bytes look like a length to me, which could indicate the start of next section, e.g. MIDI data.

From the 3rd line of your data, I can't see any regularity, i.e. it could be the mask information or in worst case the information is compressed (what I don't believe).

Can you find the first  2 letters of the song title in each lyric block? see the hotdog discussion for details.

What you have to do now is...
Find the start of a regular data block. You can try to interpret the first few bytes as offset to next block, e.g. MIDI data in case of HOTDOG.

The song entries are not the same as the HOTDOG file (.COB format?)  This is where I am stuck.  Here is part of the first song entry:
00001000   00 00 0C 41 00 00 0D F8  00 00 00 05 04 80 00 10   ...A...ø.....€..

The first 4 bytes doesn't look like the length, not sure what it's.

Any suggestion on how to decode the song entry block?
