The bands with the same name are in the same system

The famous turkish rock group “Vega” and a german hip-hop band named “Vega” (they have the same names) are in the same system. I wanted to look at the turkish band Vega’s songs and there are songs of other bands that has the same name as “Vega”. This is not just “Vega” but there are more like this. For example onr of my friends is a producer and produces music under the name of “FRTN” but I believe there was also another person named “FRTN” so they are mixed up too.
