Reference tracks are a useful tool in making sure that your mixes sound professional. The basic use of a reference track is to it as a reference when comparing your track to it. The key to finding a reference track to compare yours to is to look for a track that has qualities that you want your track to have as well. If you want your track to have a powerful low end, try to find a track that has nice sub frequencies. The main thing to remember when using reference tracks is that they are just for reference, DO NOT COPY someone else’s track just because you think it sounds good.
