Okay, I'll admit it, I've used 60 bpm Baroque music while PRing as well and found it helps me stay in Photofocus. It seems quite a few people have done so.

A related question: Has anyone used Holosyc Tapes from Centerpoint while Photoreading? There's a thread on the Paraliminal forum about someone combining Holosync with memory optimizer, but anyone had any experience using Holosync with PR?
