Whoever struck the deal to use Pink Floyd's Welcome to the Machine for the final segment of Person of Interest's season finale should get whatever they're handing out for medals in the television production world these days. It wasn't just a great move, it was perfect. From the first synth thrum, I sat up. "Hey, Pink Floyd!" A half second later I cheered out loud as my brain realized which track it was. Not only is Wish You Were Here my favorite PF album (I know, a lot of DSotM zealots are throwing stuff at their screens just about now), but it was the exact best track for the situation.
What's amazing is that the show managed to negotiate the rights. Let's face it, this is a band that (for very good reasons) refused to sell their music by the track until recently.
