Top Ten Best Resources for Discovering New Music
Not even being biased here. I only knew the popular bands like Sabbath, Dio, Priest, Maiden, Motorhead, Big 4, etc. Through this site I discovered an entire world of metal, punk, and so much more.
Song samples from iTunes is pure genius.
You can find other peoples playlists, and the related artists tab under a certain band will give you some good similar bands.
Me and my friends sometimes make lists of bands to check out and exchange them. It's a great way.
I'm not a huge redditer, but you can easily find lots of obscure bands through reddit users
Some people like Jared Dines expose underground bands, and under related videos you can find new bands.
Channels exist that specialize in exposing underground music. Like Stoned Meadow of Doom (Stoner/Sludge/Doom Metal, Psych/Garage/Stoner Rock)
I run Stoned Meadow Of Doom and it is a huge channel with over 50,000 subs now. I love it!
They have lists and stories that will expose bands, whether you know them or not to you.
You can find pretty much any heavy metal band that ever existed on this site.
It's like YouTube - you can listen for free with no registration but you can also create an account, buy songs/albums directly from the site, follow a musician, take part in discussions, forums, like/dislike songs, etc. There's also a related tracks tab.
Unlike YouTube, only music artists can upload music (their own music) on SoundCloud and for that reason the sound quality is better than on YouTube (on average). SoundCloud is the professional version of YouTube - bands upload their own songs and usually entire albums.
The best part is that very often bands allow you to LEGALLY DOWNLOAD their tracks FOR FREE (usually mp3 format). It's really easy - just click on the 'download' button (where available) and the song goes to your computer for seconds. Registration not required for the free download but you have more rights if you have an account.
Another advantage of SoundCloud is that billions of new, underground, indie music artists upload their songs on this site.
I like this site - it champions prog and power metal: videos, links, news, reviews, previews, new bands, upcoming shows. You can also buy CDs directly from the site (online store) - there are good deals all the time. This is a very intelligent site run by a metal musician.
A quick Google search can and will expose you to a whole new world of music.
This is how I found a lot of my favorite artists.
