Query: Unnessary move for Joaquin to merge with Paez!

This album is the biggest mistake in Joaquin Sabina's career. He doesn't need Paez to accentuate his music in any way. This album was a big disappointment for those anxiously awaiting a new album of his after the 1996 release "Yo mi,me, contigo". No wonder Paez is his "enemy", this album literally trashes him! I know I'm injecting my personal bias here, but Paez's singing voice got on my nerves and clashed terribly with Joaquin's nice Iberian Spanish voice, why this particular Argentinian? Well you can forgive Joaquin now, he has a new album out (1999 release) entitled "19 dias y 500 noches" and this time it's him alone sounding as good as ever.
