Daft Punk -- The only one of the three I've heard of. And I love their work, especially "One More Time" and "Harder, Better, Faster, Stronger". They had their songs in some animated movie that I saw one time on Cartoon Network back when they had the Toonami Midnight Run block (god I missed that). And without them, Kanye West wouldn't have "Stronger". *dodges trash thrown by anti-Kanye people* I'm not a big fan!
The Presets and Sam Sparro I haven't heard of.
For my three:
Maroon 5 -- I like their music, their not-too-weird-and-flashy videos, and I sing their lyrics in the shower. I haven't seen them in concert although they were in Birmingham last month (I so wanted to go too). They did a great collaboration with Rihanna.
Asian Kung Fu Generation -- I listen to Jrock a lot more than other kinds. These guys are one of my favorite Jrock groups. The vocalist tends to scream more than sing but I don't care. They really rock out loud, and they've made some of my favorite anime music.
Uverworld -- Another Jrock group, this band's music varies a lot more. And I like the way they switch between hard and soft; it makes their music very emotional.
