2. Hug: Personally, I think it is very similar to Keane's style, especially the song Gravity.
3. Because your title is English folk songs, I think King of Convenience is very independent and the folk songs are very nice.
4. Damien Rice: This is also a very independent folk song.
5.blur: Because you like oasis, the songs of their sworn enemies should also suit your appetite.
6.starsailor: as fresh as Travis and as sad as Keane.
Freedom, British band of retro garage in pete doherty, 7.babyshambles/the:. That sounds different. Personally recommend babyshambles' shotter's nations album, especially you talk and delivery. Of course, The Prodigal Son is also quite excellent, and I like Katie's best.
8.nickleback: As popular as hoobastank.
9. Stereo: This is a bit off.
10.club8: It's still fresh, independent and folk.
