So sorry to post something a little Spammy.... But I used Submithub (I am not affiliated with the site) to post some of my music for free. You can use 'standard credits 100% free' and submit your music to a bunch of blogs and youtube channels.
Anyway, I am getting featured on an asian youtube channel World Music Creation. The channel has about 150K subs. Its nothing life changing. But its cool! And 100% free.
Look up submithub, and give it a try. And while your at it click my link.. it is youtube.com It is safe. And give me some love for my big premiere!! Best of luck everyone.
