Think if you could, with your pen, write songs on a white sheet and listen to them.. ..that is exactly what Lineamp allows you to do, except you'll need your keyboard (dekstop or mobile) instead of a pen. On Lineamp you'll also have video clips, the ability to see them full screen, to save your playlists straight away as you finished writing them, to share playlists, to search for live versions, lyrics versions and much more.
