Overview

• UCI Machine Learning Repository <https://archive.ics.uci.edu/ml/datasets.html?format=&task=&att=&area=&numAtt=&numIns=&type=ts&sort=nameUp&view=table>_
• Million Song Dataset <https://labrosa.ee.columbia.edu/millionsong/>_
• PhysioBank Databases <https://www.physionet.org/physiobank/database/>_

Those look like useful additions, but I'm curious about the Million Song addition. Is it because waveform can be viewed as time series or something else? I'm asking partly because the dataset apparently doesn't include waveforms.

You are right. It's my mistake not to check this site carefully. "The dataset does not include any audio, only the derived features" is declared in the homepage. I will remove this right away.

These three repos seem data collections rather than on time-series, although some time-series datasets are contained. UIC and MillSongs are already indexed.

PhysioBank is a new source. I put it under Healthcare temporally and will move it to new physiology when this topic grows big.

Thanks
