Drag & drop any folder into the library window. Go PlayAlong will scan the folder for tab files load all compatible songs. Alternatively, you can add tabs one by one by clicking Add Song in the library header.
Check out the left menu of the library window. You can access your songs in three different views. The one called All Songs is the most compact one, while Artists and Songbooks give you a nice tiled view of artworks to start with.
As you keep practicing, a long list of recently played songs will grow under the left menu. If you're working with a set of songs, this section will be of great help for you. Without browsing your entire library, you can load songs with a single click from here.
A songbook is a collection of tabs, or a playlist, just like any real songbook. Create songbooks based upon your custom set list. In playback mode you can load the next song in your set list with a single click.
To create your own compilation, first switch to Songbooks view in the left menu. Then click on the big + mark. Change songbook title or artwork by clicking on them. Fill your new songbook with existing tabs by clicking Edit Song List or add new songs directly from your computer by clicking Add Song.
Select any song and hit space or click the play icon of the selected song. Double-clicking the song also works.
