The 'Free Fallin' hitmaker - who romanced the 'Shake It Off' singer for a brief time in 2010 - praised the 25-year-old star for speaking out about issues that affect all musicians because people listen to her.
Speaking about Taylor's decision to withdraw her music from the free streaming service, he said: ''Artists need the person with the loudest voice to speak for them.
''When you go to the Met Ball, that's great. It's a great way to use your voice and go, 'I'm wearing Valentino,' or you could use your voice to give things. Now, some people who are cynical could say, 'You're helping yourself.' But it's trickle down. You're not saying, 'I want this just for me.' I think that's a really cool thing for a musician to do.
''Like two percent of the music industry has 80 percent of all the media about it. There's like four people who get all the press, and if any of those four people say, 'I want to speak for those people who would just never make this a story'. The only reason we're talking about Taylor Swift taking Spotify on is because she's Taylor Swift! That's great!''
The 37-year-old singer also insisted he isn't worried if other artists - such as Taylor Swift - sell more music than he does.
Speaking to Ronan Farrow for MSNBC's '7 Days of Genius', he said: ''Nothing bothers me anymore. There are going to be times when I make music as popular or as empirically valued as that in terms of making pop music that won't sell as many copies. I'm fine with that.
''You get to an age where you say, 'Look, if I save a baby from a burning building and Kanye saves a baby from a burning building, there's more Google news hits on Kanye. I'm fine with it.' Now, together - and this is what I'm trying to tell you - we're unstoppable.''
