Putting a single out ahead of an album is a great way to promote your project! Here are some things to keep in mind:
- If the audio is the same for both the single and the album version of the track, they should keep the same ISRC. Both projects will need a unique UPC, however, so make sure if you have a UPC for your physical CD's, you use that for your album, not your single.
- If the album is going to be signed up for CD Baby Pro, the single will be covered too since the codes will be the same for both releases. We can administer the publishing for the single at the same time as the rest of the songs on your full-length Pro album, and can back collect royalties if they are generated in the interim.
- No two projects can have the same cover image on partner sites like iTunes, etc., so it's important to pick unique art for your single. For example, here is the album page for Beyonce's self titled album: https://itunes.apple.com/us/album/beyonc%C3%A9/780519939 . Note how the album art is different for the release of the first single off of the album: https://itunes.apple.com/us/album/pretty-hurts-single/1309037736 .
- This is also because partner sites require the text on a cover image to match the metadata for the project with which it's associated. So your single can say the name of your single on the cover, and your album can say the name of your album, but your single shouldn't say the name of your album.
