Spotify improvement suggestions (delete from shuffle list, hide songs from other artists when you enter a particular artist's page)

I've got a few suggestions for improvements to Spotify:

-Enable to delete tracks from shuffle play queue (I got a list of fav songs that I like to play on shuffle, but I'd like to be able to see which ones are coming up and delete them from the list if they don't fit well). I could just make a bunch of playlists, or arrange the songs one by one without shuffle, but it would be very easy for Spotify to just enable users to delte tracks from the shuffle queue. It might seem paradoxal that I want to customize my randomness, but I think many would like to have this semi-randomness.

-Make it possible to play only the songs of the selected artist when you enter their page (when I enter Muse's page and play with shuffle on, half of the time lotsa crappy songs from the albums where they have only 1/25 of the songs start playing). This one is linked with the one above, since I can't remove the songs I don't want from the shuffle play queue. Again I could create a new playlist, but I would have to do that with EVERY ARTIST I'd want to listen to using shuffle...
