Well, to some degree, early on, it is helpful to get a sense of what resonates with that person. Meaning, unlike TioJorge (and this is not an indictment, just a contrast) I like getting them, because it shows me something about the person sending it and how they think and what they react to. My wife and I did this a lot as we were getting to know one another.
Funny story, though, and a lesson for the kids out there.
I'm a HUGE Noel Gallagher fan. LOVE him, both in Oasis and solo, and except for one song (literally, one song; it's a Japanese Amazon only track or some shit, called "Alone On A Rope") I have every song he has ever officially released. So I thought it would be cute and informative to share a Noel song from his first solo album. We were both coming out of divorces, both dealing with ex's with anger and alcohol issues, both reeling at the end of the "dream of married bliss" and sort of wondering if this is all there is, an empty house, and no one to share it with. I thought the second verse of "If I Had A Gun..." would be PERFECT:
"Give you back the dream, show you now what might had been
If all the tears you cry would fade away (away, away, away...)
I'll be by your side, when they come to say goodbye
We will live to fight another day"
So I send the link via Shazam. Later that day I'm playing it, and my daughter goes "what's with that song?" And I said "I sent it to M******". And she says "Wow, that's a huge fail. What's with the gun thing? You want her to think you're a creeper??" I'm like, shut up, what do you know.
Later than night, we're texting as we usually did until the kids were in bed, then we'd talk on the phone. We're talking, and finally she said, "what's with the gun song? Should I be worried?" And I'm like, no! Listen to the rest of it! She's like, "Um, no."
Then about a week later, we're all together, and talking about something One Direction or something and I made a comment and my daughter says something like "Uh, dad, what do you know? You like creeper songs,", and her daughter goes "Yeah, what's up with that song you sent to mom?"
Obviously they were only busting my stones, since we're happily married now, but I still take shit for that. And Noel will always and forever be that guy with "the gun song".
