[8] According to Laura Harrell of the Orlando Sentinel, the group members wrote the lyrics and choreographed their dances without assistance.

[8] Harrell described the album as being composed of "fast, upbeat pop rhythms as well as slow acoustic ballads".

[3] MTV News' Jennifer Armstrong characterized the compositions as based on drums and other sounds effects commonly associated with teen pop.

"[9] Hollywood Records released Nobody's Angel on audio CD and cassette on February 1, 2000; it was also made available as a digital download.

[6] Its cover features the group members posing in front of a pink background, with expressions that Armstrong called "almost unnaturally happy".

[9] The group promoted it by performing as an opening act for AJ McLean and the headliner for the Polaroid i-Zone camera tour.

A Billboard reviewer wrote that the ballad had "the very essence of a hit-worthy, youth-target single", and praised its melody and the group's harmonies.

[3] Describing Nobody's Angel as a guilty pleasure, Armstrong wrote that the album had "perfectly blending voices" and "catchy tunes impossible to shake from your memory".

[9] Rohwedder thought Nobody's Angel had music worthy of revisiting,[13] though Allie Funk of the same publication wrote that the group and lead single were not relevant.
