I get why you'd want to print 'I Don't Wanna Live Forever' and stick it on a wall or tuck it in a notebook — I'm the kind of person who prints out lyrics for road trips and late-night singalongs. Legally speaking, song lyrics are protected by copyright, and copying the full lyrics without permission is technically a reproduction of someone else’s work. That doesn't automatically mean you'll get in trouble for printing a single sheet for your own private use, but it also doesn't give you a clean, universal right to do so.
When I try to figure out whether something like this is safe, I think about the four fair-use factors: purpose (personal, noncommercial use points in your favor), nature (creative song lyrics weigh against fair use), amount (printing the whole song is definitely a strike against fair use), and effect on the market (if your copy substitutes a purchase of sheet music or licensed lyric product, that also weighs against fair use). Put simply: a short quoted line or two for commentary or study is usually fine, but printing the entire lyrics of 'I Don't Wanna Live Forever' for private display probably isn’t defensible as fair use in most places.
So what do I do instead? I usually buy the official sheet music, a licensed lyric booklet, or use a streaming service that displays lyrics (those services have licenses). If I just want a poster, I look for officially licensed lyric posters or purchase a print from a seller who has the right to reproduce the lyrics. If you need printed lyrics for an event, classroom, or something beyond a tiny personal reference, contact the publisher or use a licensing service — they can give explicit permission and sometimes it’s surprisingly affordable. Ultimately, if it’s a few lines for personal study, go ahead; for the whole song, I’d play it safe and use licensed sources or seek permission so you can enjoy it without the worry.
