The Street Date is the date you want the album to go live in the music stores for sale or streaming. Not to be confused with the Original Release Date which is the first date the album was ever made available to be sold in the past. Learn more about the Original Release Date here.
During the album submission process, you will have an opportunity to set the street date for your album or single. Please note however, that while many of the major music stores (ie: iTunes/Apple Music, Amazon, Spotify etc.) are very quick in ingesting albums (Normally only a few days), many of the other music stores can take several weeks, so even though you may choose a street date, it's entirely possible that the album will not appear in some of the stores until they complete their own processing and ingestion.
If you are choosing a street date in the future (Rather than just having the album or single go live as soon as possible), we suggest setting the street date at least 14 days out to give time for most of the music stores to ingest the album.
You can also select street dates for each specific store if you want your content to go live in only some stores first and then at a later date go live in the other stores.
