Psychology behind repeated viewing of certain pictures and songs Often it happens that we like to frequently listen to a particular tune or song or view some pictures or images repeatedly time after time. What are the reasons and psychology behind this?
That's a difficult to say I assume many kind of past memories* linked with emotions subconsciously play certainly a critical role nevertheless I found an interesting link (http://www.gizmag.com/predicting-hit-songs/20939/) which is about a formula on how to find out the next hit song.



*by memories I mean more kind of episodic memories rather than semantic although it could be semantic if someone would be expressed of a song by its lyrics.
