Ryan Adams' album Rock N Roll has U2 going through it, paticularly the song "So Alive." "Burning Photographs" is also very U2y somehow... I remember once a local radio station played Burning Photographs and then played Pride right after, and I was like, wow, there is definatley an influence there.
Bloc Party reminds me somewhat of U2... So Here We Are has a sort of WOWY-like buildup. Pioneers has early-U2 style drums and sort of a UF atmosphere. Compliments has a dark, AB feel...
Coldplay probably more than anyone else is extremely U2. Songs like Don't Panic, Clocks, and Moses are so very U2 influenced.
The Killers also have a U2-influenced sound. The helicopter-like guitar and thumping bass of "Somebody Told Me" is reminiscent of 80s U2, and "Midnight Show" is very similar to I Will Follow.
Probably no one else will know this, but the Japanese artist Gackt has a song that is VERY U2, called "~Emu~ (For My Dear)" from his Mars album. For one, the bassline is basically WOWY except the last two notes, and then the first two. The guitar is similar to Streets, and there are parts that remind me of Miracle Drug (even though Miracle Drug came out later
) I highly reccomend this song.
There are plenty of others I'm sure...
