The Genius Lyric Messages feature lets you quickly combine the lyrics of a song with a photo of your choice.
Once you have iOS 10 downloaded on your phone (you also have to update the Genius app) you can create a "Lyric Message" within the Genius app and from there you can share it via text, email, Twitter, etc.
It currently only works for iMessage, but a post on the Genius blog says there are plans in the works to make it available for Android. There was no mention of a time frame, however.
I, personally, wasn't planning on updating to iOS 10 until the inevitable bugs were fixed, but now that I can send all of my best friends selfies with Frank Ocean lyrics plastered on them, I might just reconsider that decision.
