[Redesign] "Add to Playlist" List (and Album Views accessed through Genre View) loads extremely slow

Maybe this is connected to #1026.

When I go through albums within a genre view, and then click on an album and try to add a track from that album to a playlist, the selection of playlists (under "Favourites" and "Add track to a playlist"... by the way, shouldn't it by "Favorites" without the u, or are we defaulting to UK english?) is loading for like 10-20 seconds (but I currently only have 8 playlists).
Any consecutive try to add a second/third/... track of that same album to a playlist loads the playlist way faster/immediately.
As soon as I exit the album and go to the next album within that genre, the album view seems to load for longer and longer.
Same for the playlist list when the next album view was loaded and I try to add the first track of the second/third... album to a playlist.

I don't know if these are the same or separate issues, but as I experience them all at once by this action procedure, I thought I just create this one issue for it.
