I get it about the singing. While the sequels get a little weird about that, on the first one, it’s actually pretty straightforward. The Macross ship gets far away from Earth using faster than light alien technology, but then they need to go back to Earth at regular slower than light speed while also avoiding attacks from the same aliens trying to conquer Earth. A lot of the episodes are about how the crew is struggling to endure the trip and losing hope of finding a safe planet back home, so a culture outside the military duties is formed, with restaurants, services and entertainment. The main singer is just part of that entertainment and becomes the favorite idol aboard the ship. The concept of music doesn’t exist for the aliens so in a couple of occasions her songs are used as psychological warfare. That’s it. I also get having a never ending list of things to watch, anime and other things. But if you ever get the chance, at least the first series is totally worth it.
Bars, because I live in a third world country with subpar and barely maintained public transport handles aren’t even an option. I suspected what handlers are but I actually had to look them up just to be sure.
