Points are well taken but not relevant to this bunch. We are pretty close. Many of our gatherings start small but grow legs quickly. For instance, we hosted a movie night in our backyard a few months ago. The idea was first mentioned at another gathering on a Sunday. By Wed, we had confirmed 4 couples would attend. On Friday, we had 20 people show up. That is not atypical with this group. Everyone defers to me for music anyhow and often don't want to impose on me to bring gear. The Compacts have made it so simple that it is really no imposition.
The friends that were notoriously bad about music were my wife's old neighbors. If they had music, it was playing from one of their phones. We would have our Bose BT speaker in the car and suggest that we use that instead their phone. That was before I had the JBL Compacts. Now they have three young kids and live 2 hours away. We don't see them very often.
