4.24.76

य इमं श्रद्धया युक्तो मद्गीतं भगवत्स्तवम् । अधीयानो दुराराध्यं हरिमाराधयत्यसौ ॥ ७६ ॥

yah

mat-gitam
the song composed by me or sung by me

a prayer offered to the Supreme Personality of Godhead

Although rendering devotional service to the Supreme Personality of Godhead and worshiping Him are very difficult, if one vibrates or simply reads this stotra (prayer) composed and sung by me, he will very easily be able to invoke the mercy of the Supreme Personality of Godhead.
