Fucking heroes. Spotify is quick, I personally think their smart playlists are better to discover new good music. But man, I was getting so fucking sick and tired that all these tags ruined my perfect Last FM library, so when Apple Music started in 2015 I switched as quick as I could. CLEAN LAST FM HOL' IT UP
back in the day he used to produce and write his own shit, nowadays its just easier to get help from other ppl cuz he probably has way more tours & other shit to do (interviews, guest in ads etc.). That's how it goes the bigger you get, + one more thing is he has a bajilion labels behind him now which want to control what music he puts out so in the end hella people end up being involved in the project. Hope that makes you feel better about him.
