I'm sorry, but checking out the whole album is like reading the whole newspaper, then putting it back on the stand.
Amazon offers a "sample" of musical tracks that should satisfy most, or perhaps the artists own website may offer samples.
I just heard on the radio about music theft, and it's huge. it's destroying the music industry, artist income, and the next target will be DVDs.
And I do agree with Dave, legit samples are the only way to go, then if you like, go support the artist and record company, so we can still have vinyl available to us.
