Message to aliens

Alien Encounter "The Message" is a 2012 Science Channel Show.
Part of the show reports on the message that was put aboard the
Voyager spacecraft.

The message was recorded in many languages. Does this seem like the
best way to communicate with another world? If you were trying to
communicate with someone that does not speak your language, would
using more that one language seem more likely to be understood than
using a single language?

Saying the same thing 50 different ways doesn't seem like the best way
to communicate.
