If this type of thing bugs you, you can setup a playlist specifically designed to not the same play a song from the same artist back to back. (You set up a playlist for each artist under one massive playlist and set the option to only select one song from each of these artist playlists). There was a thread a couple of weeks ago about this, and it works great, as long as you don't mind taking a liitle bit of time and effort to set it up. Only problem for me is, every time I select my list I end up with at least one of the same songs. Even if there are 20-30 songs by an artist, I will often hear that same song again (only once through the list though, so you wont get the effect you had). Hopefully they will be putting in some way of preventing this in a future (post 2.0 I am expecting) release.
