Wait!!!! What's the new iTunes supposed to have???????
From the pictures on Apple website, I'm not sure if it will show top 5 or 10, but all the charting songs will be in the same display format (song titles + single/album cover). So I assume the No.1 exposure will significantly be reduced.
I don't think T5 exposure is a thing. T10 because it's on the list, sure, #1 because it's the first thing you see and there's a picture, yes. But I don't think the exact placement between 2-10 will help a song that much more.
While #1 exposure may be reduced, I think there are still people who are gonna be like, "oh look that new Rihanna song is #1 I should check it out" or whatever. I hope by "late October" they mean not until after the week of Red's release. So...October 29th or so should be fine.
