In recent decades, the Ubon style has come to dominate "lam" in Isan, while the central Thai influence has led to most songs being written in a mix of Isan and Thai. Unrequited love is a prominent theme, although this is laced with a considerable amount of humour. Many songs feature a loyal boy or girl who stays at home in Isan, while his or her partner goes to work as a migrant labourer in Bangkok and finds a new, richer lover.
