I like the design of the Simple Music Player app. It's simple user interface is really cool. Easily accessibility is one of the qualities an application must posses. As a music lover, sometimes i decide to listen to a complete album and I'm sure a lot of user do the same.
I believe some modifications can still be made to the application.

SUGGESTION

My suggestion will is that the the "Album" or "Sort by Albums" should be included the in the simple music app. It should be added as it will benefit current and prospective users.

The picture below shows an application where the Albums is used and how it is displayed (Reference: Boomplayer)

Suggestion design

The Albums feature should be added as suggested in the picture below:

After the Albums button is selected, the songs should be grouped according to their albums.

Importance of adding the feature

• Users can easily easily listen to all songs on their favorite album with just one click

• It will halt the problem of having to scroll through a long list of songs to get just one song and scrolling to look for another song that should be in one album.
• It will draw more users to the app because of the upgrade in standard and easy usability.
