מע טרינקט ניט קײן װײַן מיט געזאַנג, ביטער איז דער טרונק זײַנע טרינקער.
Rashi
For ... is dearer. Your love [is dearer] to me than any banquet of wine or than any pleasure and joy. In the Hebrew language, every feast of pleasure and joy is called after the wine, as the matter is stated, “to the house of the wine feast,”9Esther 7:8. [and as in,] “They shall not drink wine with song,”10Yeshayahu 24:9. [and as in,] “And there were harp and lute, tambourine and flute, and wine at their drinking parties.”11Ibid. 5:12. This is the explanation of its apparent meaning. And according to its allegorical meaning: It was said in reference to when He gave them His Torah and spoke to them face to face. And that love is still more pleasant to them than any pleasure, and they are assured by Him that He will appear to them again to explain to them the secret of its reasons and its hidden mysteries, and they beseech Him to fulfill His word. This is [the meaning of], “Let Him kiss me with the kisses of His mouth.”
Rashi
And muffled will be the daughters [sounds] of song. “They shall not drink wine with song.”34Yeshayahu 24:9.
English Explanation of Mishnah Sotah
When the Sanhedrin ceased [to function], song ceased from the places of feasting, as it is said, “They drink their wine without song” (Isaiah 24:9). Towards the end of the Second Temple period, the Sanhedrin ceased to function. According to Albeck, it ceased adjudicating capital crimes. From that time on, there were no more songs sung at places of feasting. Later Talmudic commentators and halakhic authorities say that this refers only to songs of love between people. Songs of love towards God did not cease, and hence it was always customary to sing songs in praise of God.
Rashi
Greek tunes never ceased from his mouth: And he should have desisted on account of the destruction of the Temple - as it is written (Isaiah 24:9), "They drink their wine without song."
