My preference seems to be things recorded in the 1970's. My favorite band is Black Sabbath. I love the drum and bass interaction on their earliest records. Another band I've become addicted to is XTC. I'm consistently impressed with the depth of their music and writing. I will say I hate some of their songs, BUT they have way more excellent material than songs I "hate". I also have a habit of posting comments on the KISS page (in their defense). Speaking of comments: I hope the overall quality of the comments sections improve. I would hope to look up a band and have a poster direct me to their favorite album OR tell others an album to avoid. This would be more engaging than: "Twisted Sister ROCKS!!!"-type of comments. But, overall I really like Pandora because it has turned me on to bands from the 60's and 70's that I never knew existed.
