As someone who also explored Lemon8's audio options, I found that the platform currently offers a limited selection of sounds by default, mostly lofi and chill vibes. However, to access trending or popular audio tracks, it's helpful to keep an eye on the app's updates and explore any new features related to audio clips. From my experience, trends on platforms like Lemon8 often evolve similar to TikTok or Instagram reels, where the community or platform curates popular sounds over time. Engaging with popular users or browsing popular posts can reveal currently trending audios that you might be able to use or replicate. Additionally, if the platform restricts audio choices, consider preparing your own audio clips or songs outside the app and then uploading them with your videos or posts, if Lemon8 allows for custom audio integration. This approach can add uniqueness and help your content stand out. I also recommend joining online forums or Lemon8 user groups where members share tips on how to optimize audio use and reveal hidden features or upcoming changes in the app. This way, you stay informed and can make the best use of available audio tools to enhance your content's appeal and engagement.
