I love being able to find #NewMusic since I tend to listen to it pretty much all day while working.
#SmarterPlaylists is a very handy tool that allows me to essentially build out my own formulas to generate playlists.
It can also schedule these formulas to run periodically in order to keep my playlists fresh for me.
I found this formula yesterday for what is basically a better version of one I had made for myself.
Running this daily provides me with a solid 6-7 hours' worth of music in a pre-shuffled mix that I can just hit play on and know that I will enjoy it.
For anyone on #Spotify that is keen to try it also, here is the link to import it. Please note that you will need to add in the "Save to Spotify" option at the end to create your playlist and then schedule it to run each morning (both of which are pretty easy to do).
