MP3Box is my personal Number 1 site to download music. The site offers a possiblity to play music (as single songs, but also full albums) online and download the content for free. If you register a free account, you will be able to add tracks to your Favourites and access them from any location, device etc. without a need to search for them again. The content will be updated daily. Mp3box has a very easy navigation and powerful search: you can browse music by artists, albums, genre and much more. No ads, absolutely free - the best site in my eyes!
MP3truck is another one good free site to find and download music in easy way. Easy track can be streamed online, added to your personal Favourite List and downloaded for free. The site has a structure of a search engine, means you can only search for music and for single songs - there is no possibility to get the chart lists or browse music by albums and artists like it's possible on mp3box.
MP3boo is another one cool site to download music. Here you will be able to find the artist with descriptions, get detailed information about his albums, browse tracks, get online streaming and download links for full albums and single mp3s.
