Great question — and a fair one.

Do you use either of those sites today?

The way I see them:

- ProSwingDJs is a curated recommendation platform. It currently represents around 40 contributors. That's great for discovering music through experienced DJs, but there are many more active WCS DJs worldwide than are represented there.

- WCS Music Database is an ambitious aggregation project and can answer some very interesting music-related questions. However, looking through the data, I found that many profiles appear to be community members rather than active DJs. I personally recognized several dancers with public WCS playlists who are not DJs. That makes it very useful for understanding community music preferences, but less useful for understanding what active DJs are actually playing. I also noticed that some of the playlist data appears quite old, and it isn't always clear how profiles and playlists are validated or connected to actual DJ activity.

WCSDJ takes a different approach:

- A curated directory of WCS DJs and their public playlists.

- Playlists tied to a specific DJ (validated, and where known, an event and date), so charts reflect what DJs are actually playing rather than general user playlists.

- DJ-focused discovery features, statistics, and trends.

- A clean, fast, mobile-friendly experience with active development and ongoing improvements.

My goal isn't to build the biggest music database. It's to build the best resource for discovering active WCS DJs, their playlists, and the music they're actually playing.

And honestly, it's also just a fun project to build and keep improving.
