Ever played Julio Iglesias Tango CD? If not, please do! Go to Amazon.com and type: tango music and then click "go" or "search".
Julio still holds having the "most romantic voice" in the singing business and you will hear it yourself and will agree that what I said is not an exaggeration! In his CD are timeless favorites like: La Cumparsita, A Media Luz, El Choclo, Yira, Yira, just to name a few.
If you don't like Julio, then you can listen to other Tango CDs there and take your pick!!!
Good luck and hope you'll find what you're looking for soonest!
