What it communicates: I'm interested but not in love with you.

Surprisingly, concert tickets are a safer option than a music mix. With tickets to see A$AP Rocky, you're not laying your soul out on the decks. You're just saying you like it, and she likes it—why not like it together? 

This is a fitting present for a girl you've seen a handful of times, and are interested in testing out the waters with. A concert isn't particularly romantic, but it's thoughtful enough to show you're interested.
