Last spring, Amazon launched its live audio-streaming platform, Amp, which aims to reinvent radio with “an infinite dial of shows.” Amp offers users access to a vast, built-in music library to create their own DJ sets with. No need to buy songs or flirt with the DMCA, just make a playlist, go live, talk in between tracks, follow the chat and even invite callers. A little over a year later, Amp is finally available on Android.
