Nnemonic Radio is a radio made by NnemonicOSTs on Radionomy.
It plays music like a radio. Predominantly tracks from or related to Mike's streams. Sometimes it plays music related to other peoples' streams or songs requested by other people. It also plays some odd and silly adverts sometimes (most of which come from the Grand Theft Auto series).
While most of the songs are from Mikes and other peoples streams, there are ones that were added specifically because someone asked them to put them in. NnemonicOSTs also seems to add in some of the more obscure or forgotten songs related to a game Mike has played as well as a few joke songs.
There are even advert music the radio cuts off to. Unfortunately we mostly don't know the songs since instead of the title it goes to "advertising".
