There is an issue with the scrollbar in playlists/albums pages. When the scrollbar becomes visible, the toucharea from the scrollbar overlaps with the toucharea of the song items, making it very difficult to select or “grab” and drag it from the top to the bottom.
You could compare it to the “Favorite Artists” page, where the right scrollbar is very easy to select and smooth to slide, in comparison to the scrollbar on the playlists pages.
