haha i used to be concerned about that too when i didn't have to many songs on my ipod. It doesn't really determine how much you like music it just determines how picky you are. I've had my ipod for almost 5 yrs now and i have less than 300 songs. some people have like thousands of songs but thats most likely because they download any song they think they like even a little bit. Also, you probably don't download full albums (i don't) unless you really like every song while others only download full albums.
depends on how long youve had your mp3. ive had my ipod for about 2 years and have close to 400 hundred songs on it. i may have had more but i buy my stuff off of itunes. plus i buy albums too. it doesnt matter how many you have. it just means that you are more wise on what you buy and actually like your songs.
