So, you spawn multiple threads to mercilessly hammer the web host of a small struggling independent radio station to get their data, and now want to share the tool so others can amplify the burden imposed on their server?

Let's see what they say on their site:

  "If you haven't recently, please make a donation today to ensure that
  SomaFM can continue broadcasting.

  Sadly we don't have some magical benefactor who made billions with
  their tech startup subsidizing SomaFM. So we need your help. Please?
  Don't make us post pictures of our DJs looking solemnly at the camera
  and begging for your support!!

  Over 30 unique channels of listener-supported, commercial-free,
  underground/alternative radio broadcasting to the world. All music
  hand-picked by SomaFM's award-winning DJs and music directors."

And then there is this:
