A really fun way to learn spanish.
Music,Music, and more Music. I love music of all kinds.. Maybe not rap that much, but I really do love music. I feel that it is good for the soul. So I take a song in spanish and I write down all the words in that song that I don't know and them words become my flashcards. And before you know it, your singing in spanish. And you know what your singing. Just have fun with it. My songs-Un Día a la vez y Levanto mis manos.

Although I am unfamiliar with the music mentioned (or am familiar with but don't like), any method that increases your exposure is good (and if it's one that you enjoy, so much the better).
Estoy totalmente de acuerdo. Diría que tu aprendezaje del español irá bastante rapido así. Te felicito. (I agree totally. I would say your learning of Spanish will go quite fast this way. I salute you).
Cuando escucho canciones de "Maroon 5" se me hace dificil cantarlas, pero las de James Blunt las entiendo casi bien, y sobre todo la pronunciacion. 
I agree, and I think there are two important things here. One, that you get exposure to Spanish from as many sources as possible. Two, that you find ways to keep it fun. Because keeping it fun will keep you doing it.
