After reading Matt's post about possible new expressions, I got to thinking about how some of you all use expressions.
What are some of the cool things you do with expression language? Do you have an interesting view scheme? Or some kind of interesting smartlist? Or some tagging apparatus? Essentially, I'm just looking to steal some ideas or think differently about how I view/list/tag what I have.
On my end, though I'm not sure it's entirely expression language, or if it is, a really rudimentary use of it, at least on my end, I use MCUtils to populate a field called "Styles" and then create interesting, genre/sub-genre-based smartlists to listen to stuff I may have accumulated but not really listened to (or not listened to in a long time)--kind of MC-as-Roon but without the graphics. So right now I have a "Britpop" smartlist and "Dream Pop" and "Shoegaze" (yes, I was in college in the early 90s) and so forth.
What kind of cool/interesting things do you all do?
