One of the many things that I love about post-rock is the way it helps me relax. It's definitely got to do with that I find repetitiveness relaxing. Yeah, I know that seems weird, but I could listen to a song that exceeds 20 minutes long, and if it's the same rhythm the entire time, i'm happy. I have also experimented with post-rock and sleep, and for me it does work. If i'm comfortable having headphones on or having a dock on, I could easily fall asleep to it. I don't do it anymore, but I used to enjoy it. I can sleep pretty well either way now. Some really good examples of what I would listen to will be posted below: You'll notice that I pick a lot of Sigur Ros songs to set examples for this type of thing, but that's just what I've always found to happen when I listen to Sigur Ros. I really enjoy them for their talent, but they're also great when you just want to sit back and relax.
