I like the shifting, shuddering sounds. My brain is making stories. I note the train or a metallic wave going by. The static has a personality. The song is haunted. Communication is not assured, but there's an attempt being made. Nice ending, too!
Some interesting haunting sounds in here, I like it, I like the sound of it coming out of the crackling and the ending bit where it goes out of control.
This reminds me a lot of some sounds that I've gotten out of Sampleson's "Scaper" and "SkyWaves" plugins. I love the classic @datamusik glitch and noise factors. 100 points for the NSFW status. Nice one!
