none of the songs in my playlist except those you cited (and they are only there to placate as I don't personally enjoy them tons) are on the radio as far as I know. At least I've never heard them there. then again I listen to the radio almost never. the radio is really crap for musical culture. even though it might seem that they have a wide spectrum through the different channels : classical, rock, house, rap. these are only stereotypes with no realistic musical categorization that in the end and sum of it all is extremely excusivist and only represents some 5% of what is actually out there over the course of all 24h, week-long and year-long. I highly recommend you go try suggesting your own new media ideas to yourself! I've found this course of action to be highly enriching.
I have a strange taste in music ( i like songs, not bands) so most of my attempts to find new music end up with nothing. I find Strobe to be a very calming song, but very little of Deadmouse' other stuff is stuff i like. Same for Garrix, galantis. It depends, sometimes it's good, sometimes it's not. Having an Itunes top 30 occasionally made interesting contributions.
