Only is used for syncing music on your iPod or your iPod like device. The rest is a bunch of advertisements and a way to suck up money, and for Flo-Rida to make a few more bucks by soaking you with $1.99 per song. Most people illegally bootleg their music using Limewire or Frostwire.
Music that conforming high school preppy girls like. Current 2009 top 40 is usually made up of silly school dance type songs, wannabe emo like Fall Out Boy and Panic and the Disco, bland Nickelback and Buckcherry type rock, some ringtone rap like Soulja Boy and R&B that obsesses on the word "shawty".
Most musically intelligent people and people outside of secondary school listen to other genres of music or the Top 40 of their choice, like country or R&B, or plain ol Rock.
Fuck this conforming top 40 type shit...I rather listen to some real talent like Jay-Z.
Basically the year when you are not yet a senior, but think you are as cool as the senior and better than the seniors. It is generally the peak of high school and kids get cocky and think they know it all. It is the first year of indepedent driving in most states, but learners permits start in different countries. To be a cool junior, you pretty much need to have your own car, and the prom is a big deal for you. It is like life or death. Junior year is also the hit in the head year, when you realize that college is only 2 years to go and you'll have to prepare for your partying by taking the SAT and get into Harvard to party.
Staci is a junior. Time to go to the prom and study for the SAT.
