to hashtag

the procedure of affixing appropriate signifiers (nouns, adjectives, verbs, adverbs, etc.) to a hashtag in order for a posting on an social media platform to be accurately catalogued for ease of referencing and cross-referencing.

You don't have to hashtag your music after you post it to Soundcloud, but it helps users find it more easily.
