"Don't Smile at Me", stylized as "dont smile at me", is the debut extended play by Billie Eilish, released on August 11th, 2017. It has eight tracks in total, six of them being singles.
The EP was re-released on December 22nd, 2017 to include the song "&burn" as the 9th track. The re-released version has nine songs, seven of them being singles.
A limited edition Japanese deluxe version of the EP was released on December 12th, 2018. It includes the songs "lovely" and "bitches broken hearts" as well as three previously released remixes of the songs on the main tracklist.
In the original tracklist for the EP, revealed by Billie on her Instagram story, "&burn" was listed directly after "watch". However, it was cut to make a place for "bellyache" due to high demand from fans.
The song was later included on the EP when it was re-released on December 22nd, 2017.
It is unknown if the song was originally going to feature rapper, Vince Staples.
Every song on the EP is stylized in lowercase letters except for "COPYCAT" which is stylized in uppercase letters.
Billie was originally only going to release the EP digitally, but due to its success, she decided to release it as vinyl and a cassette.
Three versions of the EP are available on CD. These include a promo CD made for France, a Japanese exclusive CD and a limited edition CD that were handed out to the audience of The Ellen Show.
Billie made a tour to go along with the EP called the Don't Smile At Me Tour. She also went on a second tour, the Where's My Mind Tour, to promote the EP.
The music video for "idontwannabeyouanymore" is Billie's first vertical video. The video was originally Spotify-exclusive, however, she later released it on YouTube.
The same applies to the music video for "hostage".
