Re: 6 songs on the subject of digital currencies! Have you heard them?

The HODL GANG song is the only one I have seen before and it made me laugh like some one rapping about cryptocurrencies. I believe this is just the beginning because the more adoption crypto have the more of such kind of songs we might see even against cryptos.
