In 1970 the Italian singer Adriano Celentano composed the songĀ Prisencolinensinainciusol.
What makes the song interesting is that it is gibberish, but specifically designed to sound like American English.
To an English speaker that’s very interesting because it provides an idea of what English sounds like to foreigners.
Listen to the song (it’s actually quite a fun song anyway). It does indeed sound like English – as if I should be understanding it.
