I like to play albums as wholes, however, it takes a bit of work to queue an album to listen to after the one you're currently listening to.

1. You have to queue the remainder of the current album.
2. You have to queue the entirety of the next album.

It would be interesting to be able to queue albums or switch directly from the track you're on to the next album or the one before it.

I listen the same way. When your playlist is short, you can just click and drag the album to where ever you want it in the playlist. A gray line will show you what place you have currently have selected.

If you just want to append it to the end of your playlist, just right-click on the album, and select that. Or you can scroll down to where you want to insert the album, and drag as above.

I occasionally select all the music in the playlist I've already played, and delete it. That way the list is shorter, and easier to add to.
