Before the genre became mainstream (which in itself is paradoxical) indie bands meant that a particular group was signed to an independent record label. Over time, indie music, and thus, the best indie bands, have come to be defined as a particular sound that strays from the mainstream and experiments with new sounds, melodies, and lyrics. Making some of the best indie songs of 2018, many of the top indie rock bands do remain loyal to the labels that took a chance on them when they were up-and-comers and stay on independent labels. Most good indie bands (and fans of the genre) are proud to say that they’ve eschewed the mainstream and have maintained their freedom as an indie artist. It’s a great perk to have, and all of the best indie rock bands may not have the biggest album sales – but by retaining their indie cred, it allows them to become popular beyond the scope of indie music.
