Follow to Download for Music Artists

We are building a dashboard that has features to help music artists to grow. The first lot of features we want is a follow to download feature that allows music artists give out a free song in exchange for followers so fans would be forced to connect to whatever platform they want followers on and once they click connect it will follow the artist and then they can click download to grab their free download. We would also like stats for this so the artist can check how many downloads they are gaining and a downloads section table to see all downloads created to go back and edit etc Here is an example for a follow to download for spotify. We would also like to have follow to download for soundcloud, facebook, spotify, twitter, youtube and instagram. Example: [login to view URL] We have already started the project so it should be fairly simple and straight forward, we can ahndle the design side we just need someone to code the functions.
