"Spice" is a pop album with a diverse inclusion of musical styles such as dance, R&B, hip hop, soul, rap and funk, which lead some reviewers to call it a pop collection. The lead single, "Wannabe" is an uptempo pop song with elements of white hip–hop, rap and dance music. Two of the three ballads of the album, "2 Become 1" and "Mama", were co–written and produced by Stannard and Rowe, and both feature the use of keyboards, guitars, string arrangements and backing vocals.
