Check out NoiseTrade. You can download free albums and EPs of artists you might or might not know. They provide artists recommendations for all genres based on more popular examples.
To wit: If you like Of Monsters and Men, check out The Lighthouse and the Whalers. Like John Mayer? Check out Andrew Ripp. How about Mumford & Sons? Listen to needtobreathe. Etc etc etc…
Definitely worth a look if you’re growing tired of shuffling through the same albums and don’t feel like dropping some money on new music.
And you can tip the artists if you like their stuff!
