These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
"Bless the Broken Road" had been recorded by The Nitty Gritty Dirt Band, Marcus Hummon, Melodie Crittenden, and Sons of the Desert before Rascal Flatts released it. Crittenden's version was also a single in 1997.
"What Hurts the Most" has also been released by both Jo O'Meara and Cascada. Mark Wills originally recorded it and almost released it as a single in 2003, and Faith Hill turned it down at the last minute.
Thanks to its appearance in Cars, their cover of "Life Is a Highway" is more familiar than the the Tom Cochrane original to Country Music audiences and younger people.
Critic-Proof: Every Lyric Street album from Me and My Gang onward has largely gotten mediocre-to-negative reviews for being lightweight, bland and overproduced on most of the songs. Unstoppable in particular was derided for sounding way too much like the last two albums.
Crowning Music of Awesome: "Bless the Broken Road," "I'm Movin' On" and "What Hurts the Most" are generally well-loved for being weighty, sensitive ballads.
Dork Age / Seasonal Rot: Pretty much all of their last 3 albums for Lyric Street, which (outside a few songs, such as "What Hurts the Most") were critically derided for the reasons mentioned above. However, it seems that upon the closure of Lyric Street and subsequent move to Big Machine, they have managed to Win Back the Crowd critically despite diminished returns on the singles charts.
Narm: Almost all of their Lyric Street material ever since Me and My Gang, the first album that Dann Huff produced. Most of their Huff-era songs rely on lightweight, trite lyrics that are given a wall-of-sound production drenched in strings, piano, and guitar.
Although it was their last single before Huff, "Skin (Sarabeth)" is a particularly Narmy little song about a girl who frets about going to the prom with no hair after cancer treatment... until she meets a boy who shaved his head out of sympathy and they go to the prom together.
