There’s a lot to be said about muscle memory.
I subscribed to Google Play Music in July 2013 and have been using it almost exclusively to listen to all my music since then. The only time I use a local media player on my laptop is when I want to listen to a bunch of high resolution albums I have in FLAC, which isn’t all that often these days.
So it still surprises me, then, when I find myself using — without a second thought — all the important keyboard shortcuts in Winamp!
¯\_(ツ)_/¯
