Oh Gosh. Most of them suck haha, especially Ricardo Arjona, can't stand him.

I don't like Latin Pop very much but there are some exceptions, let's see:
Belinda: nothing.
Thalía: nothing.
Paulina: even though her vocal strength is close to nothing

she has a couple of good tracks: Lo Haré Por Ti, Y Yo Sigo Aquí and El Último Adiós (the official karaoke song here in my country haha).
Fanny Lu: nothing.
Anahí: NOTHING. Is this a joke?
Enrique Iglesias: Cuando Me Enamoro (nice song) and I Like It (so catchy, even though is autotuned to death). He is a very nice guy, quite funny but he has the vocal strength of a frog.

Some of her 90s songs are classics but are painful to hear.
Dulce María: nothing, she has a nice voice wasted with silly songs.
Belanova: nothing.
Reik: NOTHING. Ewww.
Selena: nice girl, very unique. I don't like that kind of music but it's sad she died so soon.
Gloria Estefan: No Te Olvidaré (great ballad) and Más Allá (nice song, very famous during Christmas here in my country).
Pitbull: NOTHING!! Another joke?
Ricky Martin: Tu Recuerdo (I can't believe she put out a song like this,

he really gained credibility with this song) and Lo Mejor De Mi Vida Eres Tú (nice song, very inspirational).
Laura Pausini: Entre Tú Y Mil Mares (amazing song, I love it), La Soledad (awe, it reminds me of the 90s

) and Bienvenido (wow, what a powerful song

).
Shakira: almost everything pre-crossover, all the singles from Pies Descalzos and ¿Dónde Están Los Ladrones? were amazing. I used to be a huge fan of hers back then. Some of my favorites: Inevitable (her best song IMO), Tú, Un Poco De Amor, Estoy Aquí, Suerte. Since Loba her music is a big joke IMO.
Juanes: Fíjate Bien (great song full of social protest

), Es Por Ti, Nada, A Dios Le Pido. Unfortunately, he's another Colombian singer whose music is going downhill.
Miguel Bosé: only Si Tú No Vuelves. My God, a masterpiece.
La Mala Rodríguez: I have no idea who she is.
Don Omar: NOTHING. Third joke.
Christina Aguilera: Pero Me Acuerdo De Ti (one of the best vocal performances I have ever heard).
Jennifer Lopez: Una Noche Más.
Maná: Vivir Sin Aire, Te Lloré Un Río, Rayando El Sol, En El Muelle de San Blas, Ángel de Amor. Everything they have released since 2006 sucks.
Marc Anthony: I don't like his music (I hate salsa music) but I like his cover of Así Como Hoy.
Nelly Furtado: Te Busqué.
Ricardo Arjona: NOTHING!! He's the most overrated and annoying singer in Latin music history.
Julieta Venegas: nothing. Yawn.
