Putting the actual media data on the blockchain would be stupid and crazy expensive.  Media posting schemes involve putting a hash of the media on the blockchain, and the actual media is stored in a content (hash) addressable system like ipfs (or a paid CDN). 

 I would literally pay anything to upload FACK by Eminem on bitcoin 

 Putting unrelated stuff on blockchain only bloats the chain until only governments/google can afford to run a full node - so long decentralization. 

 lol I’m just trolling
