To play all of your music by the same artist
Open My Music
Select the artist folder you want.
Under Music Tasks, click Play selection.
To open My Music, click Start, and then click My Music.
When you download or copy music to your computer, Windows places music by the same artist in one folder. Windows creates subfolders within the artist folder for each album.
To play an album or multiple tracks, select the folder or music tracks you want and click Play selection. To play one track, double-click the music track.
If you click Play all in the My Music folder without selecting a folder or music track, Windows will play all of the music in your My Music folder and subfolders in random order. If you click Play all within a My Music subfolder, your music is played consecutively, according to the order of the tracks on the album.
