In Chinese there is a word called "耐聽" to describe a song that you can listen to for a million times and you wouldn't get tired or sick of it. Is there an English word suits this description? Example sentence would be "This song is ______. I can never get tired of it."
Some songs have beautiful melodies and you enjoy them at first. But only after a while you found that you've had enough of them and you do not enjoy these songs any more. You would say "The song sounds great at first. But it is not ______. I don't love it anymore. In fact, I feel sick of it now."
