I thought I found the connector
It’s just a Reflektor (It's just a Reflektor)

from Arcade Fire (Ft. David Bowie) – Reflektor Lyrics on Rap Genius

Meaning

If you continue with the motif of technology being an isolator (as discussed previously in this song), these lines could be a metaphor of how social networks, which are supposed to make connection easier, are more about yourself, and isolate you from society instead of the opposite. Rather than connecting people, they simply “reflect” the individual’s tastes.
