When you search for a band on Spotify you get the page with all their albums.
At the top of that page you find the 5 tophits.
When you are searching for new bands, you'll listen to those 5 songs to see if it is a band for you or not.
You like the band, you like all 5 songs, but there must be a 6th good song in one of those 20 albums which each have 10 songs.
I don't think many people like to listen 200 songs just to find one more hit.
That's why I suggest to remove the tophits at the top and add it as a new tab but then not a top 5 but a list of all their songs, sorted by Most Listened or Most Downloaded or whatever the current toplist is made off.
