Borislav, you're not the only one to suggest this. Being able to enter the playlist structure at the current level rather than the top level has been requested before.I know, but I haven't seen a yes/no/buy us beer first reply from empeg (might have missed it) so I thought I'd bring it up again.
In your example, you've got things broken up into genres, artists, then albums. Why does it need to be that complicated?It reflects the way I usually select music to play. I always play an entire album in order, no shuffles or random songs. I rarely know exactly what album I want to hear next, just the type of music (i.e. genre). Then I need to look at the artists in that genre to decide which one sounds appealing. Once I've narrowed it down to an artist, I need to look through the albums. Only when I see the name of the actual album I go "oh yeah, that's the one I want". So a genre/artist/album hierarchy is the most natural for me. I do the same with my physical CDs, btw.
Of course the tree isn't exactly balanced. If I want a pop album, then it's a no-brainer - I only have a single one of those

. Now heavy metal is a different story at 34 albums.
Another way to look at this is that you have to make a compromise between depth and width of your tree. If I put all the artists in a single playlist then it'll be 42 items long and a real pain to navigate (from the player).
Do you really find yourself hitting the "play" button on those intermediate treesWell, no, that was just a hypothetical example

, but I often want to select another album from the same list as the one I just finished listening to (and not necessarily the next one). Different scenario, same feature.
