So, I'll start.
Propagandhi- Supporting Caste
I was recommended this band after asking on a forum "what were some good punk bands that have great musicianship". Supprisingly, I got this reccomendation from someone on TGP. Propagandhi are a Canadian melodic hardcore band that started out as a standard hardcore band and as they've grown as a band, their sound has gotten more metal, so now its a blend of punk and metal, but it stays musical and melodic.
The song starts at about the 44 second mark- https://www.youtube.com/watch?v=fbBlnFtb8W4
Chromeo- Bonafied Lovin'
In an entirely different style of music than Propagandi, this is a band called Chromeo. I heard this song playing at a department store and I was in the changing room trying pants on, so I "shazam'd" the song. Its a band of 2 guys. Guy 1 sings and plays guitar. Guy 2 is the dj/ keyboardist. I'm not much of a hip-hop fun, but I like this song a lot. There's something almost 80's sounding about it. I also think that the main riff is lifted from an Eagles song.
