Where to shop for music?


I have been frustrated recently with the demise of a favored source for researching and purchasing music on the web. I would welcome the suggestions of others about proven sources with excellent search engine capabilities, thorough inventory of all types of music, and reasonably low prices (including the S&H charges!).

Any good experiences to relate?

When I'm looking for details of a certain album, cdnow.com rarely fails. Take the 'cd' part to heart, few records.
I suggest checking out www.pitchforkmedia.com for reviews and information. They will have links to Insound, an online cd and record seller. They have a lot of stuff others do not, including a respectable inventory of vinyl. I have found their prices to be reasonable, as are their s/h charges.
the Elusive Disc http://www.elusivedisc.com/

Acoustic Sounds http://www.acousticsounds.com/

Music Direct http://www.amusicdirect.com/

CD Now http://www.cdnow.com/

The first three cater to audiophile recordings. CD Now has few LPs, but has just about everything on CD title (non-audiophile and esoteric stuff). They have a very good classical search engine as well.
If you can't find what you want at any of the sites mentioned above, try www.gemm.com
