Bruce, Westlife and Backstreet Boys.

Objectively speaking, if Blue hadn't been dissolved, it might be on a par with Backstreet Xicheng, but it was dissolved ... In the heyday of Blue, it did surpass BSB and Xicheng for a while, but it was short-lived. ...

What about Xicheng ... How can I put it? Many of them are covers. Although some songs are very successful, I personally think that 80% of the covers are relatively unsuccessful. There are many albums and songs in Xicheng! There is no denying that the effect of the concert and the interaction with the audience are indeed stronger than Backstreet and Blue. When Xicheng was first formed, it was imitated in the form of backstreet, but as it developed, it became another style. Although the style of "Backstreet" in Xicheng is the same at first glance, in fact, Xicheng mainly uses slow songs and romantic love songs. Backstreets become more r&; B direction development.

Finally, let me talk about backstreet. Backstreet has a long life, but it's a little old now. The heyday has passed ... I also went to a concert in Beijing in March 17, and I felt really far away from them 10 years ago. Backstreet's last two albums didn't sell very well either. ...

To compare, I don't think there is comparability. All three combinations have their own strongest periods and their own declining periods.

To say 15- 10 years ago, the strongest must be backstreet!

After 2000, backstreet went downhill, and Xicheng and Blue became stronger, especially blue.

Now the strength of Xicheng should be the strongest.

PS: I'm a big fan of Backstreet, West Side and Blue. The above is just my personal opinion. These three are actually very strong.
