dowloading music from itunes or spotify

I am not good with technology…can someone assist in showing me how to download and convert to the sandisk sport player?

I am on spotify and itunes…not sure which works best.  Its been a long time since i used an mp3 player.  

Appreciate the feedback.   I am also willing to pay someone a small amount if we can connect directly.  I am in Chicago.



I am on Apple Music. And to convert Apple Music to Sandisk player, I use the Audio Converter for Windows to help me. With it, I can download and convert Apple Music as local files in other plain audio formats. Then I can sync the music to any other devices or platforms with ease.
