普通のロックと思ったけど、繰り返して聞くとくせになるって英語でなんて言うの？

- "I thought it was just an ordinary rock song, but after listening to it a few times it's started to grow on me." "I thought it was ~" 「〜と思ったけど」 "just an ordinary rock song" 「普通のロックの曲」 "after listening to it a few times" 「繰り返して聞くと」 "it's starting to grow on me" 「くせになる」・「曲が好きになる」"I'm beginning to like it." も使えます。

I thought it was just regular rock at first, but the more I listen, the more I get hooked. At first I was like, “It’s just rock,” but it’s kind of addictive once you listen a few times. It didn’t stand out at first, but after a few listens, it really grows on you. I thought it was pretty normal at first, but it’s a real earworm. 「普通のロックと思った」 ここでの「普通」は “ordinary / normal” でもいいですが、会話だともう少し柔らかく * just regular rock（普通のロック） * pretty standard rock（定番っぽいロック） * nothing special（特に目立たない） の方が言いやすいです。
