No it's not, it's absolutely used because it sounds more poetic and soft befitting of the tone of love songs, the same is true for the use of “君” and also just because “that's how it goes”. People really overthink this quirk of female singers using “僕” coming with all sorts of explanations while the reality is very simple: it's simply often done in songs just like songs feature all sorts of language that wouldn't normally be used in speech.
All these explanations of that it's supposed to sound from a male perspective or fit the metre are hogwash in many songs. There are literally character songs in musicals where female characters suddenly start singing from their own perspective and switch from “私” to “僕” for the duration of the song as well as using all sorts of other colorful language in the song they never use in their normal dialog and suddenly start pronouncing the /w/ in を like it's 900 years ago. That's just how it goes.
There are all sorts of other similar occasions too like titles of works of fiction like say “僕らのアイは気持ち悪い”, none of the characters whom the title is about uses “僕” but it's just more acceptable in the title of a work of fiction or those “narrations” that are common in love stories with female protagonists where when they narrate the story from the perspective of the future they suddenly use “君” to address the love interest and in general just speak in far more formal language. They don't normally speak like that inside of the lines itself but in narration it's just permitted to sound a little bit more flowery and poetic.
