In preparation and celebration of the launch of Apple Music, we take a look back at Apple's prosperous relationship with music from the first iPod ad through to last month's WWDC keynote and launch announcement. We've got a ton of great guests. Josh Friedlander of the RIAA chats with us about the emergence of the streaming industry, and artist manager Emily White gives us insight into Apple's relationship with artists. Dick Huey of the Toolshed marketing agency sheds light on what stats to watch, and David Pakman, a partner at Venrock, sits down for a chat about what success will look like for Apple Music.
