Applying weight to each rating based on its age seems like such an obvious fix that someone must have tried it and realized that it makes things worse.

Maybe, but I'd think you'd have to take the age weight with a pinch of salt.

The are 14 year olds who are obsessed with jazz and blues, while some 70 year olds only listen to hardcore punk and deathgrind

It also might have to do with the time span of the data set... If they only have snapshot data, it would be hard to do anything with temporal information.
