This thesis examines the crucial role that design consistency plays in shaping user

experiences within music streaming applications, focusing specifically on mobile, web,

and desktop devices. The research methodology used in this study incorporates both

online surveys and usability testing to gather insights. The study revealed that a

consistent interface design significantly impacts user satisfaction. When users transition

between devices, inconsistencies in design elements and functionality emerge as

primary causes of user dissatisfaction. This explains the need for a seamless user

experience across all devices.

Further, the research posits that maintaining design consistency considerably enhances

the usability of music applications. This consistency, reflected in the layout,

typography, and colour scheme, facilitates seamless transitions between various

devices, reducing cognitive load and promoting an improved overall user interaction.

By highlighting the importance of design consistency across devices, the research

provides a clear direction for designers in the industry. A more harmonious and

seamless user experience, brought about by design consistency, could increase user

engagement, promote user retention rates, and contribute to the overall success of a

music streaming application.

In conclusion, this thesis contributes to understanding user experience in music

streaming applications, emphasising the pivotal role of design consistency across

different platforms in driving user satisfaction and shaping the overall user experience.
