#9 web interface does not show songs with no Album tag

[Bryan Apple]

Test environment tRio 0.1.4alpha4, Jrec 0.2.5, linux.

In the Web Interface, I notice that songs with no Album
in their tags do not show up under their respective Artist
in Queue 'n Play, and do not play in Jukebox mode.

They do appear on the Rio screen (using the remote or
front keys to navigate).
