I do not agree,by listening only to your favourites you are doing yourself short.
Listen to the music you don't know and you will find new favourites,at least that is how it works for me.
I agree with both of you. There's no wrong answer to an issue that hasn't a wrong answer, only preferences.
My preference, though, is aligned with jvs. I'll check out the unfamiliar before I click on the much heard, though much loved, favourite. It's the thrill of possibly discovering a new favourite to add to the long, long list of favourites. Anyone else getting tired of looking at the wife? Just kidding!!!
