iTunes Wish List Needs Work
Although it is nice to have a wish list in the iTunes store, it looks like a grade schooler built it. You can only remove songs from page one of your list and you can not sort the entire list by artist. You can only sort the the current page being displayed by artist. So you can't browse your wish list easily. At least when I could drag the link to the song into my music list, I could sort it any way I like and it displayed my wish list songs next to my already purchased music making it easy to NOT buy the same song twice.
