One more thing, adding images for selection for genre and moods is a good idea but... see the issue first those are fixed and changing screen sizes impact on them try using cards , add text of mood for identification, add glass effect on carded images background, or try something new look for ideas on google, pintrest or dribble

I will soon be adding lint rules(will inform you) that will enforce good coding practices and your editor will help u for fixes Tip of the Day:

• cntl+'.' for quick widget tips
• shift+alt+f5 for auto alignment of code
• Commit like a pro, to improve commit history commit frequently
