Editing Playing Music

Before playing music you should select your required player via the  side-panel (squeezebox player, winamp, iTunes or foobar2000). Before  muso will look for these it will check whether you have turned them on under Options (on the Players tab).

You can enqueue whole albums by clicking on the '+' icon which appears on hovering over the cover on the Browse by Album view, by drilling down to the album and selecting the "Enqueue Album" link, or by right-clicking on an album cover and selecting the "Enqueue Album" menu option. 

To enqueue single tracks, navigate to the album or artist page and click on the track name.

From an album  or artist page, you can also right-click on a track and  select options  "Play Album From This Track Now" and "Enqueue Album From  This Track"  which enqueues/plays only the tracks in the album from the  selected  track onwards. From an album page you can also click on the track number box to play the album from that track Now (as you move the cursor over it, it shows a > icon to indicate this is a play now function).

From an album or artist page, you can  click on a  disk header to enqueue just that disc (or play it now if the  control is  pressed), or (control-)click a group of tracks by clicking  on the group  header.

You can also queue tracks directly from the database page (adds all selected tracks when multiple are selected).

===Modifier Keys (Play Now, Play Next, Randomise)===
As a general principle wherever an option is available within muso to queue music (a single track or a set of tracks) to the player:
*holding down no modifier key adds the track(s) to the end of the playlist, so is an '''ENQUEUE''' action,
*holding the CONTROL key down clears the playlist first, so is a '''PLAY NOW''' action,
*holding the SHIFT key down while activating the option pushes the track(s) after the playing track in the playlist, so is a '''PLAY NEXT''' action (Squeezebox devices only presently)
*holding the ALT key down while activating the option for multiple tracks '''randomises''' the tracks first (can be used in combination with CONTROL or SHIFT) 
Where an option is shown to play track(s) "'''''Now'''''" it will do that (the SHIFT key will not override this to play NEXT), but the ALT key can be used to randomise the tracks. Note that the ALT key cannot be used in conjunction with right-click context menus.

===Queued Music===
As  music is queued it is listed in the "Queued Music" section of the side  panel, with an indication of the total play length. The list can be cleared by a right-click option in the header. 

Note that this is not an editable playlist, and does not reflect the actual playlist order: it is only a log of which tracks have been successfully pushed to the current player (on changing player it auto-clears). Once music is pushed to your selected player it is then under the control of that player,  and the actual playlist should be edited there if necessary: a "Go To Playlist"  button in the side panel provides a convenient direct link to the  selected player's playlist). Playlist shuffling, cross-fading. etc  should also be controlled via your selected player rather than muso.

===Additional Players, Drag Operations===
Muso supports drag operations, so you can drag albums or tracks to any player that supports file drop operations to add them to that player's playlist. In this mode Muso can be used side-by-side with many additional players, though the player itself must be used for play functions (play, pause, next track, etc) and playlist manipulation.
