Comment 3 for bug 528897

yes, it still does it with beta 2; the main view redrawing for every new item is what makes it very slow

if you've ever added the folder to rhythmbox and it sees the device go away; it will add all of them at once when it comes back (thus bypassing what i described), you'll want to purge ./.local/share/rhythmbox/rhythmdb.xml (though there are other ways to make it do it, this is simplest)

as i said in the original post; picking a less often updated folder in one of the column views during the add stops it from using 100% cpu; additionally it is able to add songs much faster, as it redraws _the entire main view_ for every song if you pick the "All" entry at the top of the column views
