The problem Sync It! solves

1. Syncing your playlists across platforms(like Youtube and Spotify) automatically with one click
2. The lack of automation platforms to perform this action
3. The accuracy of the existing platforms to do this syncing job is very less, rendering them practically unusable in the first place
4. Apart from making a new playlist, we can append songs to the existing playlist as well
5. Our core mapping logic makes it easy to make more utility functions in the future to make syncing easier.

Challenges we ran into

1. Authentication flow for Youtube and Spotify while maintaining the privacy of the user!
2. Dealing with lack of Fuzzy Search logic in Spotify and thereby doing heuristic mapping on our end to ensure high accuracy.
3. Deciding on a core mapping algorithm to manage the tradeoff between the time taken and accuracy.
4. Switching between different developer accounts without much user intervention after exhausting the allowed Youtube API Quota (~converting 100 songs per day per project)
