A thought:

When it comes to music, art, vocals, songs, rapping, etc — it doesn’t need to be legible (have clear words, etc).

For example, DONDA 2 (HAPPY with KANYE/FUTURE) is very ‘illegible’ in terms of what Kanye is saying or what Future is saying. But ultimately — it doesn’t really matter what they are saying but rather the mood and the energy and the ‘vibes’ they are transmitting.
