first of all i should mention that all the songs i have on itunes are good and ones that i like, i'm not a person that just keeps every song on there just cause i have it. thats a waste of space in my opinion. why have a song on my computer if i'm never going to listen to it?
so that means that a 1star is still a song that i like, but i rarely listen to. often times its one that i just can't bring myself to delete.
2stars means the song is decent, but its not quite one i'd like to hear all the time in a random playlist, just one that i'll play when i feel like it.
3 stars are the average, ones i can't but in the 1-2 or 4-5 category, i could never argue about hearing a 3 star, but i don't looove them.
4 stars a pretty good songs, ones i listen to on a regular basis.
5 stars are amazing songs, usually that just are incredibly, or if i find i listen to a song all the time, i'll bump it up to 5 stars.
one things to mention, i am always changing my ratings..making 2s to 3s..5s to 4s...etc etc. and i try to have a balance. with the most songs being 3 stars, then 2-4 about 1/2 as mean and about 1/2 that in the 1-5 categories.
go to
