Rapid Spanish (Latin American): Volumes 1 & 2 - Earworms Learning
Very useful as a supplement. Would't want this as an only or primary source to learn, but it's helpful when you need audio only. Really well done. Some of the music isn't to my taste, but it is good quality and fades into the background pretty quickly. As advertised, helpful for getting the rhythm of the language. Instructors seem natural and casual - one seems to speak quickly and natively, and the other plays the part of the student, speaking more slowly and asking for clarification.
