Are we focusing audio signals at aliens and if so, what are we sending?

[Atypical]

Ive heard we are sending twitter messages and the music of Mozart out to specific stars in space?
Response[edit]

In 2012, on the 35th anniversary of the Wow! signal, Arecibo Observatory beamed a response from humanity, containing 10,000 Twitter messages, in the direction from which the signal originated.[13][14] In the response, Arecibo scientists have attempted to increase the chances of intelligent life receiving and decoding the celebrity videos and crowd-sourced Tweets by attaching a repeating sequence header to each message that will let the recipient know that the messages are intentional and from another intelligent life form.[14]
