So, I'm trying to figure this app out.

So, when I have wifi or 3g access I can play songs from my playlists without having the playlists synced? If I'm planning on being outside of wifi or 3g service I can download playlists to play from my phone?

Is there any way of being able to search and play music from a specific artist or album?
I tried making a playlist of one genre and then going into that playlist and typing a specific artist. It pulled the list of songs from that artist but when I select that specific song to play it just starts playing the first song in the entire playlist not the song I selected.
