Me gustas tú - Manu Chao
Although Chao is famous for singing in several languages, this 2001 song is mostly in Spanish. It's a great one for practicing the usage of the verb "gustar".

Released in 2006, "Me voy" is Venegas' most successful song to date. It features a very charming 6/8 ranchera vibe.
