that'd be cool. irc.nerds.i2p has something similar sounding on http://radio.nerds.i2p/, code for that could be available somewhere, not sure, but gives you some controls in the channel

songs can sort of be requested from http://guessthesong.i2p through playing the game in irc2p, they end up in music.simp.i2p. the code for the ircbot is jank but it's up so you could strip out the game parts and turn it into a music request bot

also just came up in #simp, if you have a safe way to bridge to larger clearnet networks, that could be useful. could help with setup if it's something you want to do
