This is an old song, or as we call: türkü, by Karacaoğlan. It is performed by Orhan Hakalmaz, who is one of my favorite türkü singers :) This is a love song like many other Karacaoğlan songs. You may remember more of his rhytmic songs performed by the band Badem.
In this song, he talks to his heart. He says: "My heart, don't go to foreign lands, because maybe it is not possible to come back. Don't be swayed by all the beauties, maybe it is not possible to love her". I hope you enjoy this touching song.
