Say it with Music
You can say literally anything with music. You can’t think of any phrase you’d ever use that doesn’t have a song. Save a chat and pick out something you joked about and search it in the music. I’ll be real surprised if there isn’t a song with that title. There is probably so many you’ll have to listen to a bunch to find the best one or the best version. It costs less than the price of a regular postage stamp but there is something about saying it with music that seems deep and thoughtful. And even someone that has a lot of stuff appreciates music.
I recently met a very successful Mesher (I made the mistake of calling her a developer, but she does this for a living and makes the things that developers use). Anyway the point is that she’s done this for years and the things she’s made are impressive as heck. So what do you get for someone like that? I sent her a note afterwards saying how nice it was to meet her and sent it with a song that I thought she would like. You pick a word or two out of their profile or conversation and you can probably find an appropriate song in just minute or two, and it says that you really cared, and were listening, especially if they like and use the song.
