Most of these artists all have a wide fanbase and I am guessing those fanbases include people who cannot afford to buy the albums, and thus turn to Spotify. Lana's name is shocking, seeing as I know not a single soul off this website who is a fan of her's in the States. People know Summertime Sadness, but most don't know the performer's name, so maybe they searched her on Spotify to get her name down? Don't hate when I speak the truth...
