What? I have hearing difficulties and have never had issues understanding the lyrics in RATM songs. I feel like they enunciate very clearly.

I eat foods of which I don't know the ingredients all the time.

Bruh English is not even my first language and I started really understanding RATM's lyrics near the end of highschool, without having to ever read them because I was too lazy cool for that. I do have pretty good English comprehension skills but I'm sure the average native speaker does better than me
