Original Challenge Description
At the last halloween party we played some guitar hero, which was a whole lot of fun and helped me to get over my fear of ghosts. Eventually we played through all the songs the game had to offer, so I decided to create one of my own. I also added a Warmup Map called Invincible, so that you can easily shred through the other one. I hope you enjoy it!

The only files relevant to this challenge are the notes.chart files and there, only the [Events] and [ExpertSingle] sections you can find in the code.
They look something like this:
[Events]
{
288 = E "phrase_start"
384 = E "lyric a"
480 = E "phrase_end"
490 = E "phrase_start"
576 = E "lyric b"
624 = E "phrase_end"
...
}
[ExpertSingle]
{
384 = N 7 0
576 = N 0 0
768 = N 1 0
960 = N 2 0
...
}
On top, the "resolution" defines how long a beat is - in this case 192 and all notes / lyrics are exactly on a multiple of that.
Solution explanation
The Invincible song contains 2^5 = 32 combinations of 5 notes.
At every time the note is played, a single letter is in the lyrics of the song.
You can observe this with the tool “Moonscraper”, a tool to build custom songs for the game “Guitar Hero”.
Then you go through the “monsters” song and every time the 6th note is played, you look up the currently pressed notes.
