Music is the great uniting force, it's an instant way to show who is or isn't feeling the mood. And to that end, is my trusty JBL speaker. Put out the call, watch how everyone reacts
>Heads bob in passing
>That one's really cool, I like it
>Hanging around to participate
>If you like X song, how bout similar Y song next?

Unfortunately they're always above healthy body weights, and I can only see that pattern so many times before putting two and two together. Either way...it saves me a lot of time in knowing who is or isn't worth talking to
>Making noise is rude
I practice what i preach. If you've got your own speaker, and it's playing stuff I hate but other people like it, go right on with your bad self
