the electric iPod acid test

A Welsh psychiatrist has claimed that some iPod users are experiencing what he calls "musical hallucinations".

Dr Victor Aziz said that the effect can occur when people spend many hours listening to the same songs. The hallucinations are characterised by a song " playing" constantly in the head, according to the psychiatrist, and the effect has caused sleeping problems for some of his patients.

Has this happened to anyone (else)? I just assumed that Kelly Clarkson really was following me around the house, repeatedly singing "Since U Been Gone" with a full band in tow. Or that somehow Brian Wilson really was singing high harmony with me on "Sloop John B." Sure, it seemed weird at first, but then you learn to just ride that wave. In fact, I--wait...excuse me a second....What's that, Neko? I should come back to bed? Ok, dear...
