I'm starting to notice a pattern with your songs.( no pun intended about the loops) They are decent loops, they simply are too short and tend to get repetitive rather quickly. Try elongating the loop to an 8 bar or 16 bar even pattern. Another helpful thing that is often done in loops to help blend the repeats is a circle progression. The best way to describe this is... every one of weebles songs. A quick google should answer any other questions about it.
