The top British bands of all time are generally considered to be the Beatles and the Stones, followed by Pink Floyd. Take a look at this: http://www.britainexplorer.com/feature-articles/item/185-best-ten-british-bands

If you like The Beatles, then you will like Oasis as well.

Westlife is my favourite.

MMm....Dificult to answer. In my case, I like very much Franz Ferdinand. And you? What's your band?

I'm sure you'll get some heated answers to this question! Traditionally, people have always fought over whether the Beatles or the Rolling Stones are the best.
