Help

This week I started downloading and posting some of Techno's vods and videos onto Spotify, as a way of listening to them on the go for me and for others. It's (expectedly) been taken down for copyright, which makes sense, but I still really want a way that I can listen to his videos for walks, roadtrips, the gym, etc. Do any of you guys know a good way to do this without needing to spend all that storage space on my phone? My friend recommended an MP3 player, but I honestly really would rather not have it come to that. I'd like to have access to as many videos as possible, and my phone screen NEEDS to be off while listening, so I can have my phone in pockets purses, schoolbag, etc
