@folkmagifili Sure -- I mean there is no Official, Sanctioned, Formally curated list of Counter Social Hashtags[TM].
User @realDDGlover has collected a list from observation -- i.e. user curation. Those are great if you want to find, like, music posts (#cosomusic) right away.
You could also make your own music or any other hashtags #neoPostModernPunk.
Finally & repetitiously: hashtags are just for search/retrieval or pin them (single or multiple!) as a column.
Hope this helps!
