Has this song become a hit by any measurable standards? Is it on the radio; it it in the charts? I fear no and no. So what is it's status and function. I was hoping it was a "hit" but that now seems ridiculous.
The Beach Boys as solo artists have never had much chart action in terms of singles (and the band hasn't for that matter either).
I don't think they expected "The Right Time" to be a hit. It was a teaser, and enticement to pre-order the album digitally. It wasn't even tagged as a "single" on iTunes or Amazon from what I could tell.
Singles charts are tabulted to include radio airplay as well. None of their solo stuff has receive much airplay. Brian had a bit of chart action in '88 with a single or two, and I think Carl had some good regional airplay with "What You Do To Me."
In any event, the only action Brian will see chart-wise would be on the album charts when the album comes out. Considering the amount of promotion it's getting, I think it will easily make it into the Top 200 album charts, and we might even see something in the top 50 or 75. I think #13 with "Smile" was the best he's done as a solo artist. So maybe even Top 40 or 30 or 20 could be possible.
