Co-written with Vidal Davis, the soul song describes a young couple's summer romance, including sexually graphic lyrics and weather metaphors.

Upon its release, the single was well received by critics, who praised Scott's vocals and songwriting, and compared her performance to those of Erykah Badu, Macy Gray, and Prince.

[5] The second verse adopts a more graphic tone, with Scott employing syncopated vocals to sing the lines "Love slipped from my lips/Dripped down my chin and landed in his lap/And us became new [...] Made the coochie easy and the obvious invisible".

[11] In an August 2000 column for Billboard, columnist Stephanie Lopez suggested that the sole purpose of the song's release was to "stir street recognition" of Scott.

[11] Lopez further noted that the "buzz" generated by "Love Rain" was benefiting "Gettin' In the Way", which rose into the top 75 of the Hot R&B/Hip-Hop Songs chart the week of her column.

[13] Also in that issue, a critic for the Dance Trax Hot Plate deemed the remix a "delicious slab of funky soul", comparing Scott's style to that of Erykah Badu and Macy Gray.

[14][15] Sal Cinquemani, writing for Slant, described the song as "drenched in thick beats and poetic sex" and commented that "Prince would be both proud and aroused" by the "love slipped from my lips" line.
