The big list of chiptune radio sites!

I've been lurking around here for quite some time, and every month or so I see someone post asking about radio sites where they can listen to chiptune music. So I finally got around to compiling a somewhat comprehensive list of all the major sites I know. Below are links to each site I've found, along with a brief description. If you know of a site I missed, comment or send me a PM with the link and I'll update this list. Otherwise, I hope you guys enjoy it!

Rainwave
I've put three years into the Rainwave chiptune radio, along with the rest of the site staff, so I'm going to indulge myself and put it first on the list. Rainwave uses a unique automated system that creates elections composed of three songs and lets the current listeners vote for their favourite. You can also request songs from the playlist to be slotted into upcoming elections. The chiptune channel plays both game soundtracks and modern original work, and receives frequent updates.

Arecibo
Arecibo isn't a dedicated chiptune site, and if you drop in at random you're likely going to hear their potpourri of VGM, remixes, and assorted randomness. The real feature is their live radio shows, two of which are exclusively chipmusic. Heossentials, Monday nights at 8:00pm PST, is hosted by the talented Heosphoros, and features a variety of great tunes. The other show, Noise Channel, is unfortunately on hiatus at the time of writing, but I'll update this post when it's back in rotation. Kris "TrueStar" Kaufman is the host, and she plays a great array of contemporary artists, as well as having hosted release parties for some phenomenal records.

Kohina
Kohina has been around for ages, and I fear it's no longer actively maintained, but the streams still seem to work. Their playlist contains a mix of 8-bit and 16-bit soundtracks and demoscene music. I always liked the vibe of this one, even if the site is kind of dated and the community abandoned.

Slay
Slay is a C64 demoscene radio station, so you're not going to hear typical chipmusic out of them. It's a category of music I'm not very familiar with, but the stream runs smoothly and they're often praised as being the best at what they do.

Nectarine Demoscene Radio
I haven't spent much time with Nectarine, but they seem to have a robust database of demoscene music and a request system for listeners, and I'd really recommend it to any fans of that kind of music.

8bitX
You've probably heard of 8bitX through their involvement with the new and prolific Chiptunes = WIN albums. Their radio hosts a number of weekly shows, including the 8 Bit Power Hour which focuses exclusively on chiptunes. I haven't listened to their playlist at other times, so I'm unable to detail what they keep on rotation the rest of the time.

Nerdy.FM
Nerdy.FM plays a broad range of nerdy music. Chiptunes, nerdcore rap, metal, rock, pop, comedy, acoustics, whatever they get permission to play. It's run by the Nerdy Show Network of podcasts and curated by Dr. Vern (of nerd rock band Sci-Fried) and Marc Sidoreus (Lo-Fi artist Marc with a C) among others. [Writeup by u/manofconsequence]

Digitally Imported

8-bit Power with DJ Bleep Bloop!
A weekly radio show featuring chiptune and electronic music. Catch it on Wednesdays from 10pm-12am EST.

NSF Radio
This one is a bit different, it's an embedded player pulling tracks from NSF files. A little more barebones than some of the others on this list, and the songs don't seem to have title tags, but it's a quick, easy way to hear some great NES music.

Chipbit Radio
A recent upstart (as of May 2014), Chipbit focuses on modern original chiptune music. The playlist is still growing, but I think this is one to keep an eye on. It has a lot of potential.
