My first little system I had LP's, 45's and 8 track. Still have my Styx Snowblind 8 track. I use playlistsplaylists all the time for teaching classes at the gym and for running and workouts. Looking forward to being able to create them on my phone through their app like Hiby. Much more efficient. And should hopefully hopefully make naming them easy too. The ability to have cueing/play once play mode would have me leave my phone in my bag while teaching, which would be nice. And my M0 in its Acco Clipped leather case survived a nice 20 mile ride on bumpy shore pavement in Avalon, clipped to a velcro strap across my aerobars. Then transitioned to my shorts for a quick two mile run. Bluetooth through my cheap Aukey headset because my IconX's didn't seem to like playing my Buckcherry tunes (great for working out by the way) directly. No issues. Sansa Clip who?
