[10] Based on his singing, Vuk Karadžić recorded some of the best poems with motifs derived from medieval Serbian history, like The Building of Skadar or Uroš and the Sons of Marnyava.
[11] Jacob Grimm was particularly enthralled by The Building of Skadar and described it as "one of the most touching poems of all nations and all times".
[12][13] He was also the source of the songs Four Uskoks, The Building of Ravanica and The Maiden Margita and Duke Rajko.
[18] In a letter Vuk wrote to Miloš Obrenović he stated that he failed to record two beautiful songs from Rashko's singing: The Wedding of Ivo Senjanin and Three Prisoners.
[21][22] In his songs Rashko paid much attention to ethics, being almost obsessed with righteousness, loyalty, and disloyalty.
