How many times did the boys of Oasis get to vote?

Beatles play second fiddle on Brit hit list
Definitely Maybe, the debut album by Oasis, has been named greatest album of all time in a British music survey, pushing the Beatles into second place.
The poll of more than 40,000 music lovers from around the world was done for annual publication British Hit Singles & Albums.
The Beatles’ Sgt. Pepper’s Lonely Hearts Club Band took second place and Revolver was in third, with three other Beatles albums in the top 100.
Definitely Maybe, which came out in 1994, featuring hits such as Live Forever and Supersonic, won the majority of votes in the poll. Another Oasis album came in at number five.
The publication’s editor, David Roberts, says voters could name as many as 10 albums.
About 95 per cent of the voters were British and the list was heavily skewed to favourite British bands, including Queen and Coldplay, and Irish favourites U2.
The biggest surprise was The Libertines’ debut album, Up the Bracket, at number 15, a showing Roberts attributes to singer Pete Doherty’s well-publicized drug arrests and involvement with supermodel Kate Moss.
The only Canadian entries were Joni Mitchell’s Blue, ranked number 73 and Alanis Morisette’s Jagged Little Pill, at number 93.
The top 10 on the list:
1 – Definitely Maybe, Oasis
2 – Sgt. Pepper’s Lonely Heart’s Club Band, The Beatles
3- Revolver, The Beatles
4 – OK Computer, Radiohead
5 – (What’s The Story) Morning Glory?,Oasis
