Have you tried another set of earbuds to rule out the possibility that something is wrong with your current headset? Do these same songs sound okay on another iPod?
Have you done any of the 5 R's of troubleshooting yet to rule out the possibility of a software glitch/errror?
I assume you haven't enabled any EQ settings?
