FrostWire

FrostWire is an Android-focused BitTorrent client. This is a powerful and free app that is not only a full BitTorrent client but also a SoundCloud downloader. To offer even more, it's also got a built-in media player. Designed for Android OS 4.1, the app has a powerful search engine built into it.

It's a relatively large file download at over 6 MB, but well worth the storage space when you do a long of music downloading. You can have all of your music downloaded to your Android mobile device quickly.
