I just discovered that "White Rabbit" by George Benson was my most played record. Since I have a large collection (probably no bigger than yours) no one record gets played that often, but I notice "White Rabbit" more; that's because it evokes so many good memories. There's a cut "Little Train" that brings back memories of me and my little "tyke" riding a little train that ran around the forest park zoo. He's bigger than I am now, but I still have those memories.
There are so many subjective reasons for our favorite music; Grant Green is my favorite artist, but you probably already knew this. The reasons beside the good music are many; same home town, he's only a few years older, that means we both listened to the same music before he became a musician.
While there are objective factors involved in the making of music, just as there are objective factors involved in almost every thing; Â as a listener I'm not concerned, unless my friend is a musician who wants to explain to me how music is made.
Enjoy the music.
