Sampathige Savaal, who had till then sung for most songs picturised on Rajkumar, fell ill. Rajkumar sang the energetic "Yaare Koogadali" for the film which became widely popular during the time and is considered one of his best songs. Rajkumar has been credited for having sung across various genres and each rendition according to the mood of the scene in the film. In "Yaaru Tiliyaru Ninna" for
Babruvahana (1977), a
prosodic form of
Kannada poetry that required the tone to be a combination of
sarcasm and anger, he blended the twin skills of theatrics and music. For
Nee Nanna Gellalare (1981), he sang two songs—"Jeeva Hoovagide" and "Anuraga Enaytu"—beginning both with the
refrain "I love you", that is full of Carnatic
gamakas. After the same tone in the refrain, they take on a life of their own with the form according to love and happiness in the former and love but a discord in the latter. His frequent collaboration with the composer duo of

Jeevana Chaitra and "
Huttidare Kannada" from the film
