Problems looking for an artist

There are some problems while looking for an artist which include copyright and genre.

Copyright
Copyright is a problem as you cannot use a song without the owner of the song's permission. if someone would use a song and haven't asked the owner to use the song they can get sued a lot of money.

Genres
Genres that we can't use include:
Rap as it would be too hard to lip sync to as it is often too fast. And often it is too explicit.
Country as it will be too hard to get the setting of the song.
Dub step as in most dub step songs there is no music so our group will not be able to lip sync.
