Good idea here. The mix down and mastering wasn't quite there, but that takes time to learn. The drums were good, but quiet. I thought the vocal samples were a little bit too quiet. The lead was overpowered, but it was a good cheery melody. The the bass line was a little weird, but I saw what couldve been a really cool bass. Again, the mixing was off, the bass had some mids and not enough bass. You did say it was quick, so i'll give you that. Overall, If you took more time to compose it, I think it would be quite popular.
