Hi all,

This is a weird one that has had me perplexed for over a year. I often play music from iTunes from my 13.3" Macbook via Bluetooth through my Sony Mini Hi-Fi system. Periodically, a song will change keys during playback and then return to its normal key. Its quite bizarre and I was wondering if any have experienced this before and know the reason. Could it be the result of a poor connection or interference?
