    Here we provide the index list of training and test recordings, considering the order of the text file "filesList".

    Unfortunately, for legal issues, we can't make all the audio files of YouTube Covers available here. Initially, we provided scripts to download the audio files directly from YouTube. However, some of the videos used to make the dataset were removed from the website. We appreciate your understanding.
    For this reason, we provide here different feature vectors extracted from this dataset. Specifically, we used the Matlab Chroma Toolbox to extract Chroma, CENS and CRP features in different frequency sample resolutions: 
0.33, 0.5, 1, 1.25, 2.5, 5 and 10 feat/s. In addition, you will need the additional file containing the lables (ID regarding the song - similar to "original" and covers). You can find all the files below:
