It seems useless to me to spoon feed someone music deemed good by one person. As has been pointed out, individual preferences abound naturally. Seems like a pointless effort.
Sadly, most folks posting here on aGon (self excluded) regarding rock music - have decent taste in it or rocks myriad of styles, as evidenced by this thread here. (Daft Punk, Alt-J is NOT rock and is case in point to the title of this thread). And yes, at the end of the day to each their own - ala subjectivity.
@OP - yep, 99% of all commercial music (reference: on radio / and on the major labels et al.) blows. I knew that by the time I was 13 yo tho... that's why I don't listen to commercial radio or buy 99% of it released by the majors (we're still talking new releases here).
If you haven't found any new music that suits you by now - you are NOT looking hard enough. If you really thought this - and did even a minimal search on the web (bandcamp/rdio/somafm/pandora etc) - a spark would ignite and send you down many many paths of discovery.
enjoy the music... there's a kid or kid's in a basement or garage somewhere, anywhere, kicking out the jams that are waiting to find an audience....
