I was gonna say your tastes are acceptable, then I saw you like Nickelback, FOB, and Linkin Park. Now you just lost points.
Having said that of recent artists I have been growing fond of Monsters and Men and Hozier (except for Take Me To Church which is played so damn much it wears on me, I just want to hear his other songs).
But Pink Floyd has an honestly immovable place in my heart. I may go for a long-ass time without listening to anything by them, but then I look back at and listen to Dark Side of the Moon, Animals, and what have you and I realize why I chose to basically grow up to them.
Warren Zevon is also someone I keep rediscovering. I used to listen to mostly just his memorable hits (see: Wereeolves of London). Then I got into his deeper stuff. And then as I get older and go deeper into his work I find more songs that resonate with me or I can get. Prior I wouldn't have understood stuff like Roland the Headless Thompson Gunner, but I think now I can at least listen to it now as a historical callback to passed modern history and get the references enough to appreciate it as a listener. On in the same vein I can listen to Lawyers, Guns, and Money with the frame of reference of a romantic perception of a bond-esque gambler in Latin America. Or Shit's Fucked Up and know then that's basically the theme to Zevon's later life and a recognition on his - and everyone else's - mortality.
And then there's on-and-off flirtation with Bob Dylan and The Doors. And off-the-radio country and bluegrass groups/musicians.
