that he made a new bass line for the track. When Madonna went to record her vocals for "Goodbye to Innocence", she started singing Little Willie John's song "Fever" instead of singing the original words. They decided to record it, as they felt it sounded good. As they did not know the words, Madonna called Seymour Stein from Sire Records, and within an hour, they had the Peggy Lee version, and the original version of the song. This song was the last to be recorded for the album, in August 1992, and it was finished within a month later. Music and lyrics Erotica is a concept album about sex and romance, on which she incorporated an alter-ego named Mistress Dita, heavily inspired by actress Dita Parlo. Musically, the album mixes dance, electronica, hip hop, deep house, ambient techno and R&B, and incorporates elements from classic disco, modern house, techno and new jack swing. Lyrically, the album played on innuendos and double entendres instead of explicit words. "Erotica" is the opening track from the album. Starting with Madonna saying "My name is Dita", she invites her lover to be passive, while she tells him to "do as I say" and leads him to explore boundaries between pain and pleasure. It deals with sex hang-ups, and has been described as "an ode to S&M". Her cover version of "Fever" follows the title track. It is described as a "sassy, house-style remake" of the pop standard. The third track, "Bye Bye Baby," starts with the declaration, "This is not a love song," and goes on to ask questions of a lover she is about to abandon. At one point, Madonna asks angrily: "Does it make you feel good to see me cry?" The fourth track from Erotica, "Deeper and Deeper," is described as one of the "pure disco" moments of the album. Its bridge features a flamenco guitar, and its lyrics talk about sexual obsession. In "Where Life Begins", Madonna promises to teach "a different kind of kiss" to the listener. In the song, Madonna talks about the pleasures of oral sex and also references safe sex. The sixth track is "Bad Girl". It talks about a woman who would rather get drunk than end a relationship she is too neurotic to handle. The seventh song, "Waiting", has been described as a "yearning ballad." Featuring spoken words, it addresses rejection and unrequited love.
