Every song, album, and playlist on Spotify has its own shareable link. Here's how to copy one:
1Open Spotify — the app on your phone or computer, or open.spotify.com in a browser.
2Find what you want — a single song, a full album, or a playlist.
3Open the share menu.
On the app: tap the ••• (three dots) next to the title, then choose Share.
On the website: click the ••• next to the play button, then Share.
4Tap "Copy link" — to song, to album, or to playlist (the wording changes depending on what you picked).
5Paste it here — open the panel (top-right icon), paste the link into the box at the top, and press Add. It'll show up on your shelf.
What a link looks like
open.spotify.com/track/4cOdK2…
open.spotify.com/album/6N9PS4…
open.spotify.com/playlist/37i9d…
The word after the address — track, album, or playlist — tells the player what kind of thing it is. You don't need to do anything with the long ID after it; just paste the whole link.
