Before you give up, consider many music sites give short clips of the songs.
I did a site for a clock store selling musical clocks --I used a small sound bite to give the viewer a taste.
http://www.clocksclocks.com/ see left menu bottom. It pops up only because the clocks are animated also.
I used Flash to make the sound clip but there are other applications that are easier to use for clips, I just happened to have Flash.
I'm sure you've seen the sound bites on MusicMatch JukeBox and other sites that sell CDs. Its not really hard to do.
