Before trying to upload a track, make sure that you've saved it under one of the supported file formats. As good practice, always go for the best quality you can provide.

• Winamp accepts WAV - FLAC files
• Bit depth: 16 or 24
• Sample rate: 44.1 or 48 kHz
• Mono or stereo
• Maximum size of a single file is 100 MB.

Any other format cannot be uploaded correctly. These requirements and restrictions have been put in place to ensure the best sound quality. After fulfilling these requirements, you can proceed to select your tracks and import them directly into the media library.
