Heartfelt love letters wherein you bare your soul to the object of your affection are so 20th century. It’s the digital age, and Spotify is giving you a new way to say I love you.

According to TNW, the music streaming behemoth is providing a service called Love Notes this Valentine’s Day, which allows users to create customs playlists with hidden messages. Whether you’re looking to be subliminal (“I secretly love you”) or straightforward (Let’s Get It On), Love Notes lets you use music to say what’s in your heart.

Here’s how it works: First, you’ll need to answer: “How hot is your message?” Choices range from intimate (Just the Way You Are) to raunchy (Bump n’ Grind). Second, you’ll be asked: “What should it sound like?” Genre options include everything from country to hip-hop. And lastly: “What should it say?” This is the sneaky part. Once you’ve worked out what you’d like to convey, Love Notes will craft a playlist where each song’s title starts with one of the letters in your message.

We tested it out at the Bump n’ Grind intimacy level, using hip-hop, R&B, and indie as the genres and the message: Y-O-U-R-E-T-H-E-O-N-E. Love Notes began with You’re All I Need to Get By by Marvin Gaye, Only Love Can Break Your Heart by Saint Etienne and the subtly suggestive Uncuff Me by n* grandjean (Y-O-U), while the remainder of the playlist was filled out with songs starting with R-E-T-H-E-O-N-E. The songs were generated almost instantly and each individual track was swapable, making it pretty easy to tinker with the finished product.

If you and the apple of your eye share a passion for music, this seems like a great way to let them know how you feel this Valentine’s Day.

Those that are into this sort of thing should also scope out Digital Trends’ Glorious Valentine’s Playlist for Maximum Sexytime. Conversely, if you’re nauseated by all this lovey-dovey nonsense, our I Hate Valentine’s Day Playlist might be just the thing.
