Tapstar. I would get it quick though because it's on sale for a limited time for $.99. There is a lite version that u can try out to and there are are actually songs from reall artists that u can download for free. Some artists r p!nk, metro station,run dmc, Britney spears, and Many more that I forget at the moment
Not that I have anything against the app, but what exactly do you mean by "real artists"? Last I heard, anyone can make music.
Sorry,poor choice of words. I guess I meant to say known or famous artists so many of songs you will know. You can download many of those songs in the lite version to see if u like any of them
