How do people get free music on their iPhone?

I've always bought my music from the apple music store, but it's expensive. A lot of people I know say they NEVER buy music! They get free music from websites or something. IIm just not sure how safe that is… What do you think? How do you download your music?

Music apps, there are plenty of free ones on the app store

THEY STEAL! The get copies from illegal websites, or makes copies from friend, who made copies form others - SOMEBODY at the beginning of all this, paid for the music. I'm a life-long career professional musician in NYS. If you steal from my colleagues, you steal form ME. So - what have got at YOUR house, that you spent a fortune on, in time, instruments, education, wardrobe, gas, etc. - until YOU mastered it - that I can come over and STEAL FROM YOU? Yes, you can free APPS to alow you to download music - but you either get ads, bad copies, or OLD stuff. You want good, new music? YOU PAY. And if you STEAL - well, *karma* will make you pay in ways you can't imagine, fella.
