Deletion of Poppy unreleased discography

Comment: Comparing one of the most recognizable and influential musical acts of all time (The Beatles) to a pop singer who released one moderately successful album (Poppy), is a bit of a stretch, wouldn't you agree? |Similar lists like this exist, as you mentioned, but those are supported by reliable secondary sources, not Soundcloud and Instagram. Perhaps Poppy -- years from now -- will warrant such a list but only when coverage can establish notability

Comment: there's barely music released to enough to warrant a split off to a separate discography, let alone a ''second'' one that documents only her unreleased material. Unreleased material can sometimes have a place on Wikipedia, but not like this with this sort of new artist with so little content released. Note how any examples listed above have been decade spanning  artists (or hugely prolific ones - Beatles released 12 albums in less than a decade.) It's also sourced to social media and soundcloud. To meet |Wikipedia's notability requirements, there should be many reliable, third party sources (professional musical critic types) that write detailed articles about her collective unreleased work. If that exists, the article certainly doesn't show it. Delete the article, but any song that can be sourced to a third party reliable source could be added to the article of the respective released music articles (''Song A was recorded for the debut album, but was left off.(reference)'') or to her respective article in the history section (''Song B was released on December 24 as a free download for fans for Christmas.(reference
