Lana Del Rey was so affected by this past weekend's mass shootings in El Paso, Texas and Dayton, Ohio, that she wrote a song in response. Late Monday, the singer posted a clip to Instagram of her singing live in studio, with her producer Jack Antonoff on guitar. The video, which has over 1 million views on Instagram, was a quick, unedited shot of the soft ballad, containing the lyrics "I'm still looking for my own version of America/ One without the gun, where the flag can freely fly/Only fireworks when you and I collide/ It's just a dream I had in mind," according to Rolling Stone. . . .
