What are your top 5 RB CDs For SQ - Rock Music

Hello, I am always on the lookout for excellent sounding Rock albums in Red Book format and over the last 3 years have gathered a fairly nice collection of my own. Unfortunately, I am begining to run out of ideas though.

After much debate and stress I have chosen the 5 Albums below as my top 5 in no particular order. This of course would have made this decision even harder then it already was:

Supertramp - Crime of the century
Led Zeppelin - II
Fleetwood Mack - Rumors
AC/DC - High Voltage
The Clash - London Calling

I would appreciate hearing about the best ones from your collections so we can all reap the benefits of our combined experiences...Thanks
