Michael Jackson has become the most downloaded artist of all time.

The 'Thriller' singer-who died of acute Propofol intoxication aged 50 last June -is the world's most popular solo star, ahead of Lady GaGa, Elvis, the Black Eyed Peas and Rihanna according to download records from Nokia's Ovi Music Store.

Musicologist Geoff Roberts believes the singer's upcoming birthdate on Sunday (29.08.10) could be responsible for an increase in his popularity

He said: "Michael Jackson has always been a pop music legend. But the anniversary of his death and upcoming birthday celebrations seem to have revived Jackson fever as fans rediscover his songs - making him the most popular solo artist of all time."

The 'King of Pop' - who would have turned 52 this weekend - is most popular in India where he accounts for 26 per cent of the country's entire Ovi downloads, followed by the UK, Germany, Netherlands and Finland.

Singer's 1982 single 'Beat It' is the most popular track at the Ovi store, with 'Billie Jean' and 'Thriller' close behind.

Meanwhile Michael's hometown of Gary, Indiana, will mark his birthday with a party outside his childhood home tomorrow (28.08.10).

The party will take place alongside a separate four-day 'MJFanvention' which began in the town yesterday (26.08.10).

The main attraction at the fan event will be a special tribute concert on Saturday, featuring Tony Award-winner Melba Moore and the late singer's former tour guitarist Jennifer Batten, as well as impersonator Edward Moss and a choir of Indiana residents.
