I was asked what "#TSIMH" stands for. It stands for "Today's Song In My Head". Back when the 🐦site only allowed 140 characters, I needed something short & snappy to append to my media posts. I think it works well. Occasionally I'll use #ASIMH for "Another song..." if I'd done more than one or more unrelated musical posts in a single day. It also allowed me to recall what I'd already posted in the past. Hashtags are cool.
