The album was well received by critics who complimented George's production and Anthony's youthful voice. Anthony received two awards for "Best New Artists" at the Billboard Latin Music Awards and the Lo Nuestro Awards. The album produced three singles: "Hasta Que Te Conocí", "Palabras del Alma", and "Si Tú No Te Fueras", all of which charted on the Billboard Hot Latin Songs chart. As of 2002, Otra Nota has sold over 300,000 copies.
RMM manager Ralph Mercado invited Anthony to record a salsa album, but Anthony declined the offer due to a lack of interest to record in Spanish. The following day, while in a taxi, Anthony was listening to Juan Gabriel's song "Hasta Que Te Conocí" ("Until I Met You") on the radio and was motivated to record in the song in salsa and told Mercado about his change of decision. Mercado introduced Anthony to Sergio George who would produce the album. According to George, the album was an "total experiment", citing that it was on low budget, recorded with one musician at a time without a band, and the full production was done on computers while George handled the keyboards.
The album includes five compositions and three cover songs. The lead track "Palabras del Alma" ("Words from the Soul") is a cover originally performed and written by Ilan Chester. "Si Tú No Te Fueras" ("If You Would Not Leave") was composed by Nelson Frank and Jaime Gutierrez. "Hasta Que Te Conocí" was first performed and written by Juan Gabriel. "El Último Beso" was composed by Anthony's father Felipe Muñíz. "Make It With You" is a cover of American band Bread's song. "Necesito Amarte" was written by Luis Castillo who composed songs for RMM recording artists including José Alberto and Tito Nieves. Sergio George co-wrote "¿Juego O Amor" ("Game or Love?") along with Adam Sez. The final track, "Si He de Morir" ("If I Were to Die") was composed by Luis Díaz.
"Hasta Que Te Conocí" was the first single to be released from the album and peaked at No. 13 on the Billboard Hot Latin Songs chart. The second single "Palabras del Alma" peaked at No. 15 on the Billboard Hot Latin Songs chart. "Si Tú No Te Fueras" was the last single released from the album which peaked at No. 31 on the Billboard Hot Latin Songs chart.
Evan Gutierrez of Allmusic gave the album 3.5 out of 5 stars and complemented Anthony's voice as "developed, unique, and individual" and felt that Anthony's debut "brought quality and passion to his listeners from the beginning." Gutierrez also found the songs in salsa enjoyable while calling the ballads. Gutierrez praised Sergio George's arrangements as "outstanding" though he felt the production was outdated in places. David Wilson of Wilson & Alroy's Record Reviews also gave the album a 3.5 out of 5, calling "Palabras del Alma" and "Si Tú No Te Fueras" as "danceable" tunes and noted "Hasta Que Te Conocí" as the highlight of the album. Enrique Lopetegui gave the album 3 out of 4 stars, noting that while Anthony was viewed with skepticism on the salsa market, he felt that Anthony "may be the best of the many newborn salseros." Lopetegui also praised Anthony's vocals as "excellent" and described the overall album as "noble effort" though he criticized Anthony's cover of "Make It With You" as unnecessary. In 1994, Anthony received a Billboard Latin Music Award for "Tropical/Salsa New Artist of the Year" and a Lo Nuestro award for "Tropical - New Artist of the Year".
