Drop in sales
Shops have reported a massive drop in single sales - they've gone down 37% compared with this time last year.
But loads of official music download sites are doing really well.
A track by rock band Muse was recently made available for 99p to web-users.
Around 5,000 copies were sold, which would have been enough to put the single in the top 40.
New top 40 planned
The music industry also has plans to launch a new top 40 based on both internet and shop sales.
It also wants to make sure that there are plenty of sites for buying music, to help stamp out illegal downloading.
