Nathaniel Okusanya, from Lambeth, London, will appear in custody at Croydon Magistrates' Court, accused of killing Kwame Ofosu-Asare.
Kwame was found with fatal stab wounds in Adelaide Close on the Moorlands Estate in Brixton, south London, on the evening of Friday March 2.
Kwame and his friend had visited a recording studio in Brixton and were on their way to the friend's relative's house when they were chased by two young men and assaulted, police said.
Kwame, who lived in Catford, south-east London, died in the ambulance which was taking him to hospital.
A post-mortem examination revealed he had died from multiple stab wounds.
