What About Flash for securly previewing music

Hi,

What are your thoughts on using flash to preview music on an online music site. What are the pros and cons. Most important I am concerned about the security of the data (music files).

I do php scripting as well and I read up on how I could pass various info e.g file name to the swf via flashvars dynamically, and then use that to stream in a track for playing.

I am not to clear on how I should go about everything, so I thought I would as you experts on the forum how would you go about something like that and what concerns I need to address.

Thnaks guys…
