If the adorable innocence of "I Wanna Hold Your Hand" or the sweet redundance of "Hey Jude" or even the grisly humor of "Maxwell's Silver Hammer" sends you soaring into your Happy Place, then you can help scientists better understand how music helps humans retrieve the long-forgotten events of their lives.

A UK-based research team invited people to visit their website and recount the first Beatles-related memory that sprung to mind. The over-3,000 memories already assembled are almost invariably positive ones, and extremely vivid in detail, according to Professor Martin Conway and Dr Catriona Morrison of the University of Leeds. Interestingly, neither age nor gender seems to be a factor in how our brains use music to tap into happy memories. "The memories were equally split between men and women, and came from all ages - the youngest was 17 and the eldest was 87," says Dr. Conway.

It was always assumed that a failure to retrieve a particular memory was the result of that memory not being properly recorded in the first place, explains Dr. Morrison. The fact that music can cue these forgotten events suggests the problem is not so much in the storage as in the retrieval.
