Spotify and Rdio are great streaming services, and unless you've become a diehard fan of the clunky Apple Music, you're probably still using them. However, if you pay for your subscription for Spotify and Rdio through iTunes, you're paying too much.
Apple charges 30 per cent for all payments made through iTunes. That means subscribing to the Premium plans in Spotify and Rdio are $11.99/month instead of $14.99/month. This is ridiculous. If you're a new user, head to the subscription pages for Spotify or Rdio, and you can sign up with the cheaper subscription fees. If you're a current user who paid through iTunes, you can also change your subscription on those pages.
