Apple Music, Pandora, and at least a hundred others. But you can't DOWNLOAD the music for free. You can only PLAY it for free. You are dreaming if you think you can download popular music for free.

I believe Google Play Music and Amazon Music have free apps for iPhone but most of the music is not free but some of the free featured albums and Antenna Sampler free indie songs on free version of Google Play Music are pretty good.
Couldn't you just use iTunes or the iTunes Podcast app to download music podcasts?
