I listen to music or podcasts while cycling to/from work everyday, but at low enough volumes that I can easily hear traffic around/behind me. I would not recommend it if you've just started cycling, but if you're comfortable enough on a bike in city traffic it should be okay. Just make sure you're always constantly aware of what's happening around you.
And wear a helmet, at the very least.
Had a huge Northern Kings phase a couple years ago. Damn good stuff.
Bantamweight's haunting cover of Nirvana's Heart Shaped Box is sorely underrated in my opinion.
ERRA's versions of Audioslave's Light My Way and Muse's Stockholm Syndrome.
Art vs Science's psychedelic-funk cover of Enter Sandman featuring a sweet as keytar solo.
Sleep Token's heartwrenching unplugged version of Hey Ya!.
And finally, Denzel Curry's supercharged version of Bulls on Parade. I didn't think the track could sound angrier but he's gone and done it.
Bonus: Andrew Hulshult's Hell March, featuring chainguns as percussion, Master Boot Record's Doom E1M1 metal chiptune remix, and GeoffPlaysGuitar's argent-metalized Halo Overture.
I saw that! Greyed-out Wolverine model bouncing off the log truck lol
