A website that has audible sample tracks?

iTunes allows you to preview songs, but only portions of the song. Are you looking to hear entire tracks?

spotify.com and mog.com if you want full tracks. amazon.com, itunes.com and emusic.com for partial tracks. I'm sure there are lots of others.

@jlind, no. I just need to hear partially samples of what EXACTLY in the CDs that I am interested in.
@Sfar, thanks. I'll look them up

All music dot com has many samples. Then Amazon does too.
Between them I can usually find what i want.
For full labums check Pandora, and just create a station with the desired artist. it may not play the exact album you want right off, but it can give you an idea of the artist's style. (and others you might also like if you like that artist)
