Hype Machine aggregates what music blogs are posting, so you don't have to follow dozens of them individually. It tracks thousands of blogs and pulls in the tracks they write about, creating a constantly updated feed of new music. You can browse popular tracks, search by artist, or follow specific blogs. The site also has a chart of the most-blogged tracks of the week, which is a useful signal for what's about to break.

Before streaming algorithms became the default way people find music, Hype Machine was how a lot of people discovered new artists. It still serves that purpose, and the human curation from blog writers gives it a different flavor than Spotify's recommendations. The site is free, and there's an app for mobile listening. It's particularly good for electronic, indie, and experimental music.
