Star Trek: The Next Generation1987

[Rasmussen enters Data's quarters, which are exploding with noise]

Rasmussen:
[shouting] What in God's name is that?

Lt. Commander Data:
Music, Professor.

Rasmussen:
Music?

Lt. Commander Data:
Yes, sir. Mozart's "Jupiter Symphony in C major", Bach's "Brandenburg Concerto No. 3", Beethoven's "Ninth Symphony, 2nd Movement, molto vivace", and "La Donna e Mobile", from Verdi's "Rigoletto".

Rasmussen:
Do you think you could thin it out a bit?

Lt. Commander Data:
Computer, eliminate program one.

[music thins, but Rasmussen shakes his head]

Lt. Commander Data:
Computer, eliminate program two.

[music thins more, but is still too loud]

Lt. Commander Data:
Computer, eliminate program three.

[Rasmussen gestures for him to lower the volume]

Lt. Commander Data:
Computer, half volume.

Rasmussen:
[still shouting] How the...!

[pauses, realizing the volume is low enough]

Rasmussen:
[much quieter] How the hell can you listen to four pieces of music at the same time?

Lt. Commander Data:
Actually, I am capable of distinguishing over one hundred and fifty simultaneous compositions. But in order to analyze the aesthetics, I try to keep it to ten or less.

Rasmussen:
Only four today?

Lt. Commander Data:
I am assisting Commander La Forge with a very complex calculation. It demands a great deal of my concentration.
