Is that what you took away from the quote? I sounded to me like he was trying to solve a problem some girls have... when they're sitting around talking or heartbroken, it is helpful to have an easy way to listen to a playlist that fits with their mood, and that is what Apple Music provides. He's not saying all girls do is talk about boys or are shallow, I think he was giving a real example (most girls do this) and providing a solution to the problem of not being able to instantly procure a fitting playlist. Unless you were being sarcastic, which seems more likely.
Having a lot of female friends, and I do mean a lot.... I can totally agree...
I've watched many of my female friends try and pick music that fit their fluctuating moods between sadness and rage during a breakup.
I've sat with them, consoled them, listened to their stories, listened as they went over the same stuff multiple times, providing a shoulder to cry on, and encouragement.
One minute they'll want music that is about how terrible guys are, the next a song about how much they miss someone, and then a song about how he deserves the rage that's coming, and then how things will work out.
Breakups are tough. Some women take them hard. Some go through a roller coaster of emotions that range from taking the guy back, to killing him, to feeling sorry for them, to making them pay for breaking their hearts, to wanting to work things out, to how worthless he was as a man, to back to killing him, then back to getting back together.
And the music they listen to tends to follow the same pattern. I can't tell you how many times they've played the same song and told me how it relates to something with that man. And how many times they've asked me to help them pick music when they wanted a different song.
Perhaps letting them hit play on a playlist made for that would be nice. I'm not a bitter person, and I'm very happy by nature. So helping someone find the right sad song isn't my strongest skill.
Letting them start a playlist that's already there would allow us to focus more on the talking and processing of feelings.
