2018 has hit its mid-point, and in the first six months of the year, some of rock's biggest acts have added to their impressive catalogs, with both Shinedown ("Devil") and Three Days Grace ("The Mountain") extending their run of rock chart-toppers.

This year has brought the return of A Perfect Circle and Scars on Broadway after long layoffs and seen the emergence of such stellar new bands as Bad Wolves, The Fever 333, Thunderpussy, Ledger and Vexes. Plus, Alter Bridge's principal creative forces -- Myles Kennedy and Mark Tremonti -- released outstanding new music.

Join us as we revisit some of the songs, both well-known and under-the-radar, that deserve to be celebrated as 2018's Best Rock Songs ... So Far, and revisit this post as we'll update the list throughout the year.
