Hi Aakash Budhiraja,
I believe http://www.kaggle.com/c/msdchallenge is the challenge you’re referring to. If so, then the challenge is to use existing user information about some of the songs in MSD to predict which other songs in MSD a given user would listen to. In fact, they give you half of the listening data for many users, and you’re to predict the other half for the same users. So yes, you would use the entire MSD and try to find a subset of songs from it based on another subset given to you. And no, it would not be sufficient to work with a subset. Furthermore, Kaggle gives you song IDs only, and MSD contains the pairing of song IDs with corresponding song metadata, which could be helpful to making more accurate predictions.
I hope this helps.
- Tom
