Hmm... Yeah this is weird. It works on posts on our main site, but doesn't seem to show on Hive. Could be something having to do with the HTML capabilities of Hive. It has worked in the past so that's why we published the post... Something with the last hard fork might have changed things up...I am seeing the controls on Peakd.com and getting same results on a test post, and not even seeing it through the BlockTunes front end...Strangs... But yes, you can certainly share the IPFS link using Hive which works and is a decentralized way to share your music. You did it right.
