Featuring different music genres, from electro to hard rock, music festivals attract hundreds of thousands of music lovers every year. Here’s a look at the five best music festivals from around the globe:

Stretching on for 11 days, from late June to early July, and featuring performances from 700 bands, on 11 stages, Summerfest has been certified by the Guinness Book of Records as the World’s Largest Music Festival. Between 800,000 and 1,000,000 people invade the 75-acre Henry Maier Park on the lakefront, to be a part of the festival.

Summerfest was conceived in the 1960s, by Henry W. Maier, mayor of Milwaukee, after visiting Oktoberfest, in Germany. Ever since then, Summerfest has been featuring local and international music talents, from a variety of musical styles.

Known as one of Europe’s most important music festivals, EXIT attracts around 200,000 people to the superb Petrovaradin Fortress, in Novi Sad, Serbia.

EXIT Festival was created back in 2000, by three college students, as a form of protest against the former Serbian president, Slobodan Milosevic. It has a come a long way, from experiencing serious financial difficulties to winning the title of best European music festival of 2007. This year, State of EXIT featured performances by Lilly Allen and Arctic Monkeys, among others.

Set in the truly gorgeous Naeba Ski Resort, Japan, the Fuji Rock Music Festival has often been referred to as “the cleanest festival in the world” or “the most beautiful festival in the world”. It was inaugurated in 1997 and was held at the bottom of the famous Mount Fuji, but, even though it was then moved all the way to Naeba, the name remained unchanged.

Over 100,000 music lovers gather in Naeba every year, to listen to over 200 Japanese and international performers, making Fuji Rock the largest music event in Japan. With a very impressive line-up, Fuji Rock still has a very pricey admission fee, around $400.

2. Roskilde – Roskilde, Denmark

Held in the same place where people attend the annual “Naked Run” for a ticket to next year’s festival, Roskilde is one of the most important music festivals on Earth.

Roskilde Festival was created by two high-school students and a promoter, back in 1971, and it attracted mostly Scandinavians. Nowadays, people come from countries all around the world to hear some of the most popular bands perform. The 2009 line-up includes artists like Coldplay, Nine Inch Nails, Kanye West and Oasis.

I’m not exactly what makes Glastonbury Festival of Contemporary Performing Arts so special. Maybe it’s the countryside setting, in southwest England, or the rainy weather that turns the place into a bog, or the top-class performers that never refuse an invitation to perform. Whatever it is, one thing is for sure, Glastonbury is recognized by most as the best music festival in the world.

The 2009 edition of Glastonbury was attended by almost 140,000 people who paid around $250 to see artists the likes of Bruce Springsteen, Blur, Franz Ferdinand and Black Eyed Peas, perform on more than 80 stages. Over 700 acts are featured at Glastonbury every year.
