The wheel is one of my main con's with the C5, which in general I like.
It is difficult to naivete through thousands of songs with the wheel, or for that matter, hundreds of albums.
While we probably cannot change the hardware UI of N5 at this point, but we welcome suggestion from users, so in your experience, which is the better UI design to naivete through thousands of songs or hundreds of albums? We'll have new DAP roll our or redesign our existing DAP in the future, so your suggestion might be our important asset down the road.
Déjà vu.
This conversation can be found in every DAP thread where the device has a scroll wheel.
The solution is to format your library into groups. Make one folder for artists a-d, make another for e-h, and so on. This reduces the scrolling by a ton.
FiiO users have been doing this for years.
In my experience, we tends to operate very efficient when we scroll through 2-3 pages content, and efficiency will slow down when we deal with 4 pages onward, and will start o frustrated after we go beyond 7-8 pages. Given N5 will display 6 lines of content in one page, I recommend we organize our Music Library with a folder structure that will have not more then 20 items in one level, and when we have 30 items or more, we should regroup them into smaller folders, and once we need to deal with 50+ items, we'll easily run into frustration.
For example, my current folder structure is 4 levels by nature:
Level 1: Language + M/F/Group/Genre (e.g., Korea male, Hong Kong female, English Group/VA, Classical, ...)
Level 2: Artist
Level 3: Album
Level 4: Title
In normal case, Level 2 Artist and Level 4 Title might go beyond 30 items, therefore I might need to break down the Artist into one more level if needed (Artist A-D, E-H as you suggested). For level 4 File Title, I normally will group all file in single or 2-CD album into one folder, but for Album with 3 CD or more, I'll break the album into CD1, CD2, CD3 etc.
This sound complicated, but once you get organized and get used to the arrangement, you'll find it pretty straight forward to maintain and efficient to use.
