I thought you had to pay for music that you buy. Like $1.99 or so. I’m on an Android.
Well, Gee, moovova, one always has to pay for music that one BUYS. . . but if you already have CDs one can simply rip them into iTunes. . . or find MP3s elsewhere and import them. iTunes will search your computer for any music that is already on your computer and import it for your use on any iPod, iPhone, or iPad, or to stream to an AppleTV or HomePod. You can also legalize any ripped music you have through iTunes by paying Apple's monthly music subscription which also allows you to upgrade all those low sampled bit rate MP3s to the highest available sampling rate available for no additional cost. . . but that's an option one doesn't have to subscribe to.
