How do you resist the temptation to hit play on new music instead of going back to old stuff you already know you like? Lastfm shows that 35% of my scrobbles went to my top ten artists in the two years I had my account there. The number drops to 21% if I restrict the results to the past 12 months, but it's still a problem I have. Started making a spreadsheet for all the music on my computer which I think has helped.
Are you conscious about giving preference to the latest additions to your library, or does this not even require effort for most people?
Forgive me having fully explored neither DMX's nor NWA's catalogues yet.
