Madonna experimented with more folk and acoustic music in Music (2000) and American Life (2003). A change was noted in the content of the songs in Music, with most of them being simple love songs, but with an underlying tone of melancholy. According to Q magazine, American Life was characterized by "a thumping techno rhythm, liquid keyboard lines, an acoustic chorus and a bizarre Madonna rap." The "conventional rock songs" of the album were suffused with dramatic lyrics about patriotism and composition, including the appearance of a gospel choir in the song "Nothing Fails". Madonna returned to pure dance songs with Confessions on a Dance Floor, infusing club beats and retro music with the lyrics about paradoxical metaphors and reference to her earlier works. Madonna moved to urban direction with Hard Candy (2008), mixing R&B and hip hop music with dance tunes. MDNA (2012) largely focused in electronic dance music, which she has embraced since Ray of Light.
