So I'd like to add an artist to the database, except this artist has the same name as, is from the same country as, is in the same genre as, and is contemporary with an artist already in the database. How do I differentiate?

If they are different decades, use the decade to distinguish them. These are the guidelines I currently use for artists with duplicate names:

1. If the artists with the same name are from different countries, use the two character ISO country code to distinguish them. e.g. (CA)

2. If the artists with the same name are also from the same country, use their active decade to distinguish them. e.g. (70s)

3. If the artists with the same name are also from the same country and the same decade, use the genre to distinguish them. e.g. (Jazz)

4. Nothing yet exists...

The object is to enable visitors to know the right artist from their name without having to drill through to the discography (which is why numbers aren't suffixed instead).

Avishai Cohen vs Avishai Cohen

Same name, same country, same genre, active around same time.

Honestly the album I had in mind by the latter Avishai Cohen wasn't even all that great so I can just not add it

In this case, I'd just do what Wikipedia have done and use bassist / trumpeter to distinguish them.
