Levent Yüksel is a very famous Turkish pop music singer. He is also a bass guitar player. He performed many songs of other pop music singers as a back vocal singer. Many of his own songs have a special sense of humor. This song is kind of fun. "Bi' Daha" is the story of a husband who drinks with another lady and then regret what he had done.
In the name of this song, we see an apostrophe. This is because we Turks say "bir" (one) some fast, and it becomes as if we said "bi". Because of this contraction, we put an apostrophe in the writing language. "daha" means "more". So "bir daha" means "one more". "tövbe" is "repentance", or as an exclamation: "Never again!". He says "One more? Never again!" :)
