Overall, the Amazon music app has a minimal design interface, it offers many functions to provide users with a more comprehensive listening experience, such as “Like/dislike”, “Alexa”, “Customers Also Listened To”, “X-Ray” etc., but having too many functions without mappings and constraints at the same time might confuse users and reduce the easiness of use.

Combine the Repeat, Repeat track and Shuffle buttons into one icon to minimize the chance of inappropriate actions and maximize efficiency (figure 6). The solution is to limit the number of choices users can choose to act upon. At this time, if users switch to the next song, the repeat track mode will automatically be turned off. But when users switch to the previous song, the icons remain the same. Having the Repeat icon and Shuffle icon simultaneously is confusing to users. When the shuffle mode is on, users can still tap the Repeat icon twice and enter the repeat track mode. But it does not provide users constraints. Two signifiers on the player page (figure 5), the Repeat icon and Shuffle icon, indicate the affordance of repeating and shuffling the song. Repeat, Repeat track and Shuffle icon figure 5 The solution is to switch the downward arrow to a left arrow and add a swipe right option (Figure 4). The signifier of the return button should be modified, and the swipe affordance should be added. Following the concept of mappings, the users should swipe right to go back to the previous page, however, this page does not offer swiping right option or button, instead, users have to tap the downward arrow to go back, which means collapse/slide down refer to the knowledge in users’ head. When the users tap the music queue icon on the bottom left corner (Figure 3), the Previous and Upcoming song list slides out from the right side of the screen. The solution is to add an interactive motion in response to the tapping action (Figure 2). However, when users click on songs or any button, it does not give Immediacy of feedback as the “Filters” button does, the users do not know if they tap the right button until the player page pops out. The animated icon instead of the number signifies to users which song is playing.

The blue icon right next to the name of the song signifies to users that the song has been downloaded. It is easy to navigate to the “Filters” button on the top right of the page, tap to expand/collapse the “Sort by popularity, duration, and title” filter, showing which has been added to the library/downloaded, which song has lyrics, and which has been purchased by users. The Album page (Figure 1) has a simple design to ensure visibility and discoverability. Feasible redesign solutions are provided.
