What are some good songs?

I like stuff that's really deep, talking about crushes, love, falling for someone, or someone falling for you. Artists or bands I like are hey monday, cady groves (she'e awesome but kinda not very well known although she has a voice like cade), everything taylor swift, demi lovato, colbie calliat, paramore, avril lavigne and songs like that. i like other types of music too but this is what I mostly listen to. i don't need any song suggestions from these artists, I have everything of theirs already. Who are some artists similar to them? I need stuff to download! Thank you. = )
