4AM Mulholland is the second extended play (EP)[2] by American R&B singer Amerie, released on October 19, 2018, through Feeniix Rising Entertainment.

[5] Maura Johnston of Pitchfork said the EPs "fuse Amerie's thoughtful craft to R&B's current wave and reveal more pleasure with each listen".

[3] Johnston acclaimed Amerie's vocal range on the tracks "Curious" and "A Heart's for the Breaking", and summarized that "On first listen, the sprawl of sound takes center stage as it does on so much modern mood music.

"[3] Jeff Benjamin of Billboard wrote that the content of the EPs "pivots from her pop-leaning past hits into a deep dive of more subdued, cavernous R&B and trance-laced productions".

Benjamin felt that "Curious" sets a "moody, mysterious tone", and called "A Heart's for the Breaking" a "snappy, trap-heavy cut".
