Once you have the its search results you can scroll through and select your song of choice. One unique feature that is offered here is that you can stream the song prior to downloading in order to ensure that it is the song you were searching for. This is highly recommended as not all of the songs are properly tagged within the engine itself. There is a lot of irrelevant search results that get returned so make sure you stream the song to ensure it is the correct song.
Overall, I would recommended this app for download since it is free. The search results can be inaccurate at times, but this is a nifty tool to have when your on the go and do not have time to transfer music to the phone, or if there is a song that you just cannot wait to listen too.
