O yes, I like them both as well! Both are by Caceres, so I felt I had to choose between them, and that became 'tango negro' this time.... But you're right, 'Toca tango' is a classic as well.
I agree, La Mulateada is No. 1... With Podesta, of course... I love very much Del pasado with DArienzo... And Yo me llamo “Juan te quiero”... Beautiful song...
An extra 'thank you' is required. This video, "Tango Top 5: Modern Milongas!" Helped me a lot! It explained the feeling I have had since I started dancing Tango in 2007. You are helping me a lot. Hope to talk with you soon.
Also if you hear Portuguese folk from the North, you will hear Milonga. It would be worth to mention it more than as a "spanish" origin wich is totally wrong.
