BitSong is a new music platform, which will be built using the Ethereum blockchain and the IPFS distribuited filesystem. BitSong is a project dedicated to musicians and listeners and will generate profit for the artist and the users who listens to their songs while creating a money saving opportunity for advertisers. The user will be paid for the "User Attention", the producer will receive earnings in real time, the advertiser will be able to optimize the campaign after viewing the reports. Our vision is to create a new revolutionary brand linked to music streaming that is unlike any other platforms. Our goal is to be present on any Smart TV equipped with Chromecast, through Smartphone app stores, on any personal computer through a web interface or software and finally any car equipped with a Smart Radio.
