for that I expect to get that)

Only thing I can say on 3 is the interface is pretty not bad. I've never quite liked it, but it has never really gotten in the way. I only recently started trying the track/artist mix. Also can say it's okay. I've actually found a few gems over a few weeks of usage, but at the same time I have found times where it's time to skip to the next track, though this is mostly due to personal taste and not because it's throwing some really out of character into the playlist.
