Nice song and a cool video. Welcome to Hive. It's a bit different to other social media, so check out what others are doing. Lots of Brits here and plenty of bands and musicians.
You can paste a Youtube link into a post to embed the video. Also, you can 'cross-post' to communities in the @peakd and @ecency front ends. It is frowned upon to post the same thing multiple times unless you decline rewards on the copies as each item should only earn rewards once.
It can be worth verifying your Hive account with a link from something like Youtube as we do get people posting stuff that is not theirs to get rewards. You can register than here.
Have fun!
