Well they aren't terrible, but they definitely don't produce top notch music. In general electronic music is slowly going to shit through mainstream catering, and pleasing the masses. Can't blame those DJ's though, its hard to say no to money. This particular song for example, is a clear cut case of ripping off other successful songs with the same main beats/sounds.. which in all honesty were just as terrible as this one. I guess to each his own, this type of music is played at clubs and leaves memorable times when the majority of the crowd is dancing to this on drugs.
IMHO, people should check out less mainstream artists, and actually do some research rather than download music straight of the beatport top10.
I'd recommend: Gui Boratto, Henry Saiz, Trentemoller, Edu Imbernon, Jan Blomqvist, Maya Jane Coles, Florian Rietze, Paul Kalkbrenner, Gesaffelstein.
If you prefer faster and more upbeat music, a lot of mainstream dj's do in fact put out good tracks every once in a while, however it's usually not the ones in the top10. Sander Van Doorn, Michael Woods, TyDi, Mark Knight etc. there are tons. N imho all better than the 2 you mentioned.
