Los Angeles funk band Vulfpeck  wants to go on tour, but they're going to need your help to raise the  money. This isn't some Kickstarter: They've made an entirely silent  album designed specifically for the purpose of siphoning cash away from Spotify's treasury. Its a clever stunt, and it just might work. 
Here's the deal: The band released a 10 track record called Sleepify  on Spotify. Each song is just over 30 seconds long, and they're all  completely silent. The idea is that you can leave the record playing  while you sleep, they'll make $4 overnight.
