I've heard of Lady Gaga, Taio Cruz and Owl City and unfortunately don't really like any of them.. sorry. Although Lady Gaga does have her moments, I don't have her on my iPod or listen to her if I can help it but if somebody's playing it in the background it's not that bad, like I can appreciate it. Bass Hunter I had to look up and I wasn't a big fan of them either.
Sorry I feel really bad after you liked Collect Call and stuff, but yeah, thanks for the recommendations anyway :)
