Good to know I’m not alone. I’ve used it since (according to the app) 1/14/17 and have amassed 51d 7h of listening time. I feel like I’ve used it since around 2014 or so, but I could be wrong. I know somewhere around that time there was a platform switch and stats got lost.
In any event I was overjoyed when they grandfathered me to a lifetime subscription after switching to a paid model. I truly, deeply appreciate this app and all the work they put into this.
