One thing I like to do occasionally is listen to tracks that are live recordings, either in front of an audience or not, it doesn't matter. To do this, I filter my songs by playing tracks that contain - either in the Artist, Song Name, Album, Comment or Grouping - the words "Acoustic", "Unplugged" or "Live". This, I find, saves me a lot of time going through all the songs on my playlist that aren't pre-recorded. It's like a live concert through your speakers with all your favourite artists! Yay!
