That being said, there is a Google search query you can use to find downloadable music right in your browser without having to use any P2P applications.
The search query is as follows:
intitle:"index.of" (mp3|mp4|wav|aiff|aac|wma|flac) search.string.here -htm -htm -php -asp -cf -jsp
Replace the text "search.string.here" with the artist or song title (separated by dots) for which you are searching.
For example, if you want to search for The Nutcracker Suite by Tchaikovsky, you could use a search query like this:
intitle:"index.of" (mp3|mp4|wav|aiff|aac|wma|flac) tchaikovsky.nutcracker.suite -htm -htm -php -asp -cf -jsp
Then, you just go to a page in the search results, right-click the file you want to download and choose the option to save it.
