I say no. simply because a label is just a theme by different artist(s).

RAW vs. Top Shelf
SUF vs. Cluster
Kiddaz vs. Killaz
Hydraulix vs. Apex
Mosquito vs. Rise Robots Rise
Shark vs. PGV
MaxMin vs. WahWah
Skankelic vs. ...

then theres a whole load of individual specialist labels that do lots of artists:

Tresor, Warp, DJax, Drop Bass Network, Expressillion 4x4, er... Fresh Grind, Holzplatten (er... shit, acid techno?) - well you get my drift.

The all provide you with some guidance - even better when they drop an artist in you've never heard before - the start of a journey, skating into new tunes and appriciation of wider themes within techno.

anyway - it also allows artists to work out what sells and what doesn't. Labels are brands - something punters love.
