She helped raise funds with "Nordeste já", a Brazilian version of the American charity efforts "We are the World" or "USA for Africa". The 155 choruses of voices recorded a compact disc with two songs of hers, "Chega de Mágoa" and "Seca D'Água". In May 2006, in a pocket show at "Bourbon Street Nightclub" in São Paulo, Simone and her band performed for the "Credicard Project". Notable recent performances include the ones in Peru, where the audience stood by the stage clapping for more than five minutes straight; and in Miami, along with Ivan Lins. By June 2007, the "Coliseum of Santos" received an icon of MPB who had once been a resident. "Amigo é Casa", sharing the stage with Zélia Duncan, was a show for the recording of an eponymous DVD and aimed to mark the partnership she had with Zélia Duncan for the past two years. Her repertoire includes some 350 interpretations, one of the largest among Brazilian female singers. The themes of romantic love and passion ("Começar de Novo, Jura Secreta, Corpo, Medo de Amar nº2, Raios de luz", and "Lenha"), samba ("O Amanhã, To Voltando, Disputa de Poder, and Ex-amor"), and religious songs ("Cantos de Maculelê, Reis e rainhas do Maracatu, Então é Natal, Ave Maria", and "Jesus Cristo"), are the frequent in her work. During her childhood and teenage years, the main influences on this romantic repertoire were Roberto Carlos, Maysa Matarazzo, Dolores Duran, Ângela Maria, and Nora Ney—names of the "samba-canção" or "fossa" ("gloom") genre. Samba-canção preceded the bossa nova music style, with which Maysa was associated, and had presented more gentle or soft melodies and interpretations. Maysa's legacy, even with its bossa nova bias, is that of a more dramatic singer and it would be more properly linked to the bolero and samba-canção rhythm. Simone's fondness for boleros results from this musical heritage. Among her albums recorded after the 1980s, those that stand out include "Simone Bittencourt de Oliveira" (1995), featuring ballads among other classic and consecrated samba composers; "Café com Leite" (1996), a tribute to Martinho da Vila; "Seda Pura", an incursion into pop (2001) and "Baiana da gema", a tribute to Ivan Lins (2004)--works regarded as a reunion of a more refined repertoire and more selective arrangements.
