It's good that you're taking the opportunity to listen for yourself, rather than buying based on reviews or other opinions of personal preference. If possible, I suggest you burn one CD with about 10 tunes in the genres of music you prefer, so you can just sit back and listen without having to get up and change CDs. Just make sure to burn the CD at full bandwith and not MP3!. Enjoy and trust your ears as to what sounds the best.
