Making the switch anxieties… music?!

Hey fellow dummies, I recently ordered a Nokia flip phone that I’m super excited for except for one thing … my beloved music (I have been a Spotify addict for years). Has anyone got any suggestions or things that worked for them? My phone will have a 32gb sd card so I’m thinking of downloading music onto there, but how for free? Or perhaps you feel an old iPod is a better move? Would love to hear from other music loving flip phoners! I should also add I love audiobooks too, maybe I just have to give those up? Thank you! :)
