Hey y'all! Is there a standard hashtag for sharing 50/90 songs around the internet (Soundcloud, YouTube, etc)?

#50/90 won't work because of the slash.
#5090 may be convoluted because it's just numbers
#FiftyNinety is my favorite, but you don't see that on the website anywhere

I guess there's no "right" answer, but curious what your thoughts are!
