Where do I get MP3s from??

[nutterbutsquash]

Want to put some music on DS leappad 2, have seen how to do it but can't actually work out where to buy the 'hits' he's after. Specifically, Never ending story and summer of 69. Happy to buy them if necessary but just not sure where! All the places that come up in search look dodge.

There's plenty of legit places to buy mp3 tracks. But I tend to use Amazon as they are usually cheapest.
