I have downloaded a lot of songs from iTunes, and the list of songs I really want but can't find on iTunes, just keeps growing. I'm pretty sure the songs are available somewhere on the internet, but some are not actually on albums, and so I can't find them in the library either. I know about limewire and other sites like that, but is there anywhere that I can buy these songs on the internet legally? An example of the type of songs I'm looking for, is One Way Or Another by Jesse McCartney. I would be very grateful for any help, thanks.
