It's a bit more complicated - if an album is flagged as a compilation it does have a folder of its own - so I could play everything in the album. But if it's not a compilation, but an artist's album with guests, e.g. Calvin Harris' 18 Months album - it's not got a single folder, and in the album view it shows up 11 times, because 10 of the tracks are "Calvin Harris Featuring ....". Hope that makes sense.
So this is what I've found.
When I first ripped my CD collection (a task from which I still bear scars), clearly it was far easier to stick to one folder structure, rather than changing it from rip to rip. This is still the structure I have on my NAS. And if I buy a new CD (not so common these days), that's still where it goes.
But it's a big old NAS with lots of room, so I have a separate folder in it (and backed up elsewhere), with my WiiM USB stick structure "For WiiM USB". I've copied everything into there, then created my own structure.
In it I can do what I want, and duplicates aren't an issue. I don't have any Calvin Harris, but if I did, I'd have a Calvin Harris folder. And I'd stick
18 months in there as one album folder, because if I wanted to listen to Calvin Harris, I'd probably want
18 Months in the same place as all his other stuff. Obviously, if when you've ripped that album, and for whatever reason it's ripped into different folders, it's pretty easy to just stick them all in one folder.
It takes a short while at first, but unless you have 500 CD albums, and every one is similarly containing guests, it shouldn't be too bad.
And I'd rename that folder "Harris, Calvin". And I'd put it in the 'H' folder (or for me it's the "F-L" folder).
And let's say you have a Kelis folder. You can copy the
18 Months album folder into that, and delete all the non-Kelis tracks from it (or not, if you think you might want to listen to them all if you're in that mood). Up to you.
And if you want to create a separate "Harris, Calvin and Kelis" folder, you can. And if you wanted to create a "Kelis and Calvin Harris" folder, you can.
Or you don't have to. Or you can do them all, or just one, or whatever combination you want. Pick and choose, you're in control.
You'll then only ever have to use folder view again, with the exception of if if you have a track on a compilation, and you can't remember which compilation. In that case, go to track/song view, and search the track title.
Once you get your head round it, it's very liberating indeed.
You don't have to change your original rip settings, either. You can keep it exactly as it is. And if you buy a new CD, you just have to copy that one CD over into your "For WiiM USB" folder.
