@Alfch most metal songs. There's a bunch of them but if I had to pick, songs by
dragonforce Through the Fire and Flames might be good since they're pretty lengthy and geared towards fantasy if you need to pull away from reality.
Disturbed if you need it to be more like heavy rock. Usually the easiest introduction.
Apocalyptica if you like cellos.
Rammstein's also a popular choice. I really can't say much about lesser known ones because there's a whole lot of them and I'm in the opinion that this genre, unlike others, are in that weird mix of popular but not really so I dunno.
If you want metal versions of famous songs, then try looking into
Frog Leap Studios' YT channel or Alien Ant Farm.
If you're looking for something just generally bops, then have a go at
Steam Powered Giraffe's music, like Latum Alterum or Hot on the Trail. Mystery Skull's also great like their song
Ghost.
For something pretty upbeat, try
Goldfish's songs like
Three Second Memory or
Kill It 4 the kids by Kill the Noise.
If you're into something funky, try
Ghost's Square Hammer or
They Might be Giants Ana Ng,
Don't Let's Start, or
You're on Fire.
If you like some 80's vibe, try
I Don't Know How But They Found Me's songs, like
Choke or
Sugar Pills.
For something a bit more chill, there's
Gorillaz'; try
Let Me Out.
If you want rock, then
Siames is also pretty great. Try
The Wolf for starters.
If you need instrumentals, I gotchu, too. Try
Wings of piano from
Deemo if you're looking for something that's not classical.
Parodies are pretty great too. Check out
The Merkins. Their parody of Faith,
Fate, was pretty great and their singer in
Man In A Box really captured Alice in Chains.
Weird Al Yankovic's also pretty famous. I particularly like
Word Crimes and
White & Nerdy. The Youtube channel,
thelonelyisland, really bops, too.
Cartoon songs are surprisingly catchy, too. Try Disney's
Powerline songs or
Quest for Camelot's If I Didn't Have You. Well, famous one's aside, Spies in Disguise kinda went under the radar but their songs really hit the spot.
Rocket Fuel,
Freak of Nature and
Then There were two to kick things off.
How bout rap? If you lean on the heavy side of things, I can recommend
NF.
Vin Jay for melodic raps or
One-T & Cool T's The Magic Key.
You like jazz? Try
Robyn Adele Anderson's covers.
There's also country. Not everyone's cup of tea, but the blues are great. Just try
Blues Saraceno's Grave Digger or
Nick Nolan's Life of Sin. Raury makes great songs, too, like
Devil's Whisper.
How bout we go to something that just screams, "THIS IS THE INTERNET!"? Try the
Chicken Song by
J. Geco.
Anime covers? Try
Maki Oyama's version of
Cha-la Head-cha-la.
I don't have a particular song preference, but I do tend to like blocking out the world, so if you're interested, dm me and I'll send you my youtube playlist. I skipped out on R&B and other pop songs cause, well, they're popular so I think you already know most of them. I suggested the ones most people I come across haven't heard of.
