Query: Great Music - Beware - Copy Protected Disc!!!

Kala Ramnath delivers, as always, stellar and flawless playing with deep, emotional maturity. Vijay Ghate's playing is crisp and tight. Excellent sonic production values throughout. The big problem here and reason for the low star rating (which pains me greatly - it would easily garner 5 stars) is the annoying copy protection software embedded on the disc. I bought the disc, can't I manipulate the data to suit my personal needs? I'm not interested in selling it to anyone! I'll spare you the rant on copy protection. Just be forwarned that this disc is in my opinion, greatly compromised by the copy protection.
