In Muse's song Endlessly, the lyrics embody a sense of unrequited love, unfulfilled longing, and a painful but persistent dedication towards the one they love. The singer has an intimate part of themselves that they refuse to reveal to anyone, including the one they love. The love described is not limited by boundaries as the singer is willing to give everything and love the person endlessly, but they also won't let go or leave them falling. The singer's dedication to the one they love is unconditional and never-ending, hence the recurring use of the word "hopelessly" throughout the song.

The lyrics imply that there is a lack of reciprocation or acknowledgement from the person they love towards the singer's feelings, leading to a hopeless and unfulfilling love. The lyrics "It's plain to see it's trying to speak, cherished dreams forever asleep" reinforce that the singer's love is unrequited and they are unable to express their innermost feelings towards the person they long for. The repetition of the second verse, "hopelessly I'll love you endlessly," emphasizes the unyielding dedication of the singer.

The lyricist's use of metaphors and repetition makes the song relatable to individuals who have experienced unrequited love or have loved someone despite the lack of reciprocation. Overall, Muse's Endlessly is a poignant yet relatable song that highlights the beauty and pain of hopeless love.
