There were some excellent examples mentioned above including Video Killed the Radio Star which is a personal favorite of mine. I would like to suggest a more contemporary example, Guns and Horses by Ellie Goulding. The third single from the debut album of English singer-songwriter Ellie Goulding is about everything as Goulding claims. She wrote the song about a relationship that started on-line 'you found me, at a screen you sit at permanently' but as a whole she criticizes how technology can introduce you to a wider range of people but at the same time potentially ruin the relationships you already have and will have.
Looking a long way into the future, one of the theoretically scariest songs ever is "In the Year 2525". Consider these excerpts:
In the year 3535
Ain't gonna need to tell the truth, tell no lies
Everything you think, do, and say
Is in the pill you took today
In the year 5555
Your arms are hanging limp at your sides
Your legs got not nothing to do
Some machine is doing that for you
Now it's been 10,000 years
Man has cried a billion tears
For what he never knew
Now man's reign is through
But through the eternal night
The twinkling of starlight
So very far away
Maybe it's only yesterday
"Video Killed the Radio Star" is an excellent response. Radiohead's classic OK Computer is not quite as explicit as that one, but it evokes a lot of anxieties about modern life, especially in the chilling robotic spoken word interlude called "Fitter, Happier." I think the Talking Heads covered the subject in a number of their songs. A funny song about technology (literally) taking over is "Robots" by Flight of the Conchords. While they are a parody group, it's still a great song.
One of the songs that occurs to me is “Big Yellow Taxi,” which includes lyrics about the effects of chemicals and cutting down trees on our society. The line about putting trees in a museum is very affecting. It strikes me as a pretty effective commentary on how technology has changed our lives.
Your post reminds me of The Buggles' #1 song from 1979, "Video Killed the Radio Star." It was the very first video shown on American MTV and tells the story of how technology (TV) reduced the power of music on the radio--just as future events have done since the song was first released.
I don't know if this song is any help to you, but internet friends by knife party makes me think about how social networking sites and the internet in general has taken over our lives and know it's so easy to get the wrong impression of someone because some things are read out of context.
