Good news! Streaming services are starting to give credit where it's due. That means, among other things, showing who wrote every song.
Typically, songwriters are listed using real names--not stage names or rapper names or band names.
Don't worry if you use a stage name--your real name won't be displayed prominently as an artist name or anything, but it will be displayed when a listener views the credits or lyrics of a song.
For example, see the 2 Chainz the song "Bigger Than You (feat. Drake & Quavo)" on Spotify (here). As you would expect, the artist names are listed as:
- 2 Chainz
However, if you look at the credits for that song on Spotify (here's how), you'll notice those artists' real names are listed as songwriters. Their real names are, respectively:
- Tauheed Epps
- Aubrey Graham
- Quavious Marshall
