@Chimera: that’s not the problem discussed here. I can’t confirm it, but you should create a new thread for it.
Back on topic:
1st problem: it’s known, and I really hope it’ll be fixed. It may be harder to fix than it seems, though.
2nd problem: Peregrine is right, it’s by design, you have to browse Artist -> Album -> Song. However, I think this design is flawed. I created a thead for discussion here.
