I went to Amazon.com. On the plus side:
1. I like the idea of samplers that showcase several artists of a similar music genre. I thought this a great promotional tool for new and upcoming artists. As I'm usually opposed to free downloads and artists losing out, this did help ease the guilt. As a customer it's also a good way to trial new tracks.
2. Also the site was very easy to navigate.
3. Another great feature was that there were customer reviews for most offerings.
On the minus side:
1. There was very little popular music available, chances are the track you are after is not part of the free downloads.
2. Also when I tried to download one of the samplers I found it appeared the free downloads are available only to people living in the US.
So not really useful to recommend to patrons. Personally I think I will stick to downloading the old fashioned way, from the CDs. Will probably pass these sorts of queries on to the younger members of the team, although I have made a list of the sites that I can refer to if I have to.
