Same idea. These aren't my favorites necessarily but I do like them all. It more shows how far in each direction my tastes go, without making stuff up
Enya - as far into a classical/new age sound that I go (I also like Jim Brickman and some others)
Carcass - as heavy into metal as I go, even though I wouldn't list them in my top 40 metal bands (but I still like a good amount of their stuff)
NWA - as deep into hardcore rap as I go
Cure - since their sound is really diverse anyway (alt pop to goth), it covers alt for me
Cat Stevens - one of my favorite folk artists, shows I also like Simon & Garfunkel, etc.
I tried to make all five be very different from each other too, as best as I could, while still putting artists I don't just "kinda like" to "make a point".
