The song "Yesterday's Winner Is A Loser Today" by Ernest Tubb talks about the transient nature of success and love. The lyrics emphasize the idea that while the world admires winners, there will always be losers left behind. Tubb questions why he should worry when his partner leaves, as winners may become losers in a short span of time. The protagonist admits to struggling with playing fair in relationships and wonders if his partner genuinely cares for him or if their love was just a game. He suspects that his partner still holds feelings for someone from their past, which makes it difficult for him to believe in their love. The protagonist wishes things were different, but realizes there is no other option. He must accept that he is now the loser after being the winner in the past. The song concludes with the protagonist bidding farewell to his lover, acknowledging that it is easy to fall in love but difficult to forget. He advises his former partner to remember his story and accepts that he is now a loser. The lyrics highlight the fleeting nature of success and love, reminding listeners that even winners can eventually become losers.
