I'm a rythm gamers worst nightmare

I have on-hold this mapset because:
The mapset has issues with metadata.
- Title should be either "I'm a rhythm gamers worst nightmare" or "A Rhythm Gamers Worst Nightmare" depending on where the audio was sourced from [different titles on Youtube and Newgrounds, likely go with the second as it is a more official release]
- Tags must contain the genre of the song
- Difficulty name scaling is rather unclear in my opinion
There are issues with one or multiple difficulties in the mapset.
- Apply a 30ms offset
